Crowd sourcing data is a laudable approach. Crowd sourcing data and putting it one a map seems like a good idea. Crowd sourcing data and putting it on a map without any verification or checks? You might not end up with what you originally intended.

This is a lesson that Benadryl, the hay fever medication, has sadly learned the hard way. At first sight it seems innocuous enough; a hay fever relief brand teams up with the UK's Met Office to crowd source areas where there's a high pollen count.

Finally Summer has arrived in London just in time to coincide with the annual population exodus known as the summer holidays. But wait. When you arrive at your holiday destination, how do you order a beer? If you're lucky, you'll remember some rudimentary French or Spanish from your school days. But what about other languages? Surely there's a map for this essential information?

Luckily and to paraphrase the mantra of there's an app for that, there's also a map for that. Whether it's beer, bier, cerveza, pivo, birra or øl, this handy guide to beer throughout Europe and its environs will help you get that first cold beer of the holiday into your hands.

If you live in a city for any period of time, you form a mental image of what quantifies certain areas or neighbourhoods. If someone mentions, say, posh London, I instantly think of the area around Mayfair and Knightsbridge. But you could put this personal and biased view on a map?

It turns out Yelp has done just that, producing a heat map of my home city of all the reviews that mention posh. It looks pretty much as I'd imagine.

On the way through South Kensington Tube station this morning, I spied a new Underground map. That's nothing new, the Underground map seems to be changing frequently these days. But this map was very noticeably different.

There was no Victoria or Jubilee lines at all. The Piccadilly line terminated at Hammersmith and Finsbury Park and had stations that have been closed for years; Brompton Road, Down Street and York Road. The Central Line stopped at Liverpool Street.

A standard WordPress install is incredibly powerful and flexible. For a lot of people, WordPress out of the box plus one of the stock WordPress themes is enough. But the possibilities for customization are endless; you can add plugins and other themes. Sometimes these do just what you want. Sometimes you need to ... tweak WordPress.

A very high proportion of the customization advice you'll find on the web starts with these lines ... add the following to the end of your theme's functions.php or even worse, advises that you modify the source code of your theme or your plugins. This is bad for many reasons:

• Editing your theme's functions.php makes theme specific customizations; change your theme and your customizations will no longer get loaded.
• When your theme and plugins get updated you'll find all your careful hand crafted customizations get overwritten and lost.
• A lot of theme and plugin authors won't offer support for changes you might have made to the source code.
• Your customizations might work; but you might also inadvertently make some other changes which will stop things working.

WordPress doesn't yet support a way for site specific customizations to be made and loaded without touching theme, plugin or core files; that's why I wrote WP Customizer and that's what this plugin is for. When WordPress does support such a way, this plugin will thankfully be obsolete.

Some uses of maps have remained relatively unchanged through the ages. We still use them to find out where we are and how to get somewhere else. Governments still use them to say "this is mine, that is yours". But as our planet has now been pretty comprehensively mapped, we don't use them to say "I got here first" that much anymore.

Which makes maps that prove that someone really did get there first extremely coveted and extremely valuable in about equal measures. The combination of value, national pride and good old human greed also makes early maps a fertile breeding ground for trickery and fakery.

The discovery of the fourth continent, after Europe, Asia and Africa, seems to have had more than its fair share of controversy.

Popular opinion holds that Cristoforo Columbo, better known as the anglicised Christopher Columbus, got to America first in 1492. Of course first is a loaded term; Columbus may have been the first European to set foot in the Americas but he certainly wasn't the first human on the continent. But did Columbus get there first?

Probably not; there's now growing evidence that a Norse expedition, led by Leif Ericson, landed on what is now Newfoundland in the 11th Century after being blown off course by a storm when travelling from Norway to Greenland. According to the Book of Icelanders, compiled around 1122 by Ari The Wise, Ericson first landed on a rocky and desolute place he named Helluland or Flat Rock Land, which may have been Baffin Island and then sailed for a further two days before landing again in a place he named Vinland, often mistranslated literally as Wineland but more likely to mean Land with Great Grass Fields.

Of course it would help if there was a map of Vinland, to underscore the I got there first point.

There's a new version of Google Maps for the web but so far it's not for everyone. You need to request an invite and not everyone gets one of those it seems. But if you're impatient or curious and don't mind a tiny amount of technical hackery you can get to test drive the new version without the need to be one of those blessed with a preview invite.

If you go to Google Maps right now, you'll still see the current incarnation of Google's map. This is what the map of my home town looks like. The new preview version is there, you just can't see it.

Governments and authorities like maps. They're a useful way of clearly saying this is mine, that is yours. They're also useful for saying where you can and more importantly, where you can't go. This is all too evident in a surprising map of where Russian visitors to the US were permitted to visit during the 1950s.

In the mid 1950s America and Russia were in the middle of the game of oneupmanship, with added nuclear weapons, that was the Cold War. Despite the uneasy detente between the two countries, if you were one of an elite group of Soviet citizens you were actually able to visit the United States. But not all of it. Large swathes of the US were closed to prospective Soviet tourists.

In January of this year I made a hopeful prediction that 2013 would be the year of the tangible map.

This hope was prompted by the maps I saw at one of London's geomob meetups in November of 2012, where I saw and, importantly for a tangible map, touched Anna Butler's London wall map and a prototype of David Overton's SplashMap.

The hopeful prediction was made as a result of literally getting my hands on one of Anna's London maps and it's a treasured possession, though still sadly needing a suitable frame before it can take pride of place on a wall at home.

But what of SplashMaps? In November 2012 the project was on Kickstarter and I was one of the investors in this most tangible of maps. In December 2012 Splashmaps met their funding targets and went into production and today, through the letterbox came my own, tangible, foldable, scrunchable and almost indestructible SplashMap of my local neighbourhood.

The boundaries of Europe's constituent countries have changed a lot in my lifetime. Some countries don't exist anymore whilst others have come into existence. But it takes a map visualisation to make you realise just how much the map of Europe has changed.

Actually, it takes two map visualisations. The first, courtesy of the BBC, dates from 2005 and covers the years between 1900 and 1994. Starting wit Imperial Europe and fast forwarding though two world wars, plus the Cold War and taking in the collapse of the Communist Bloc and the expansion of the European Union.
