Although I can't find the originator of the saying that there's no delete button for the internet, it's a saying that's very true. If you put something up on a web site, be it a photo, some text or perhaps a file of geographic data there's a very good chance that someone else has a copy, even if you subsequently take the original down. It's a sort of digital whack-a-mole.

This is all too apparent in the story of Yahoo's GeoPlanet Data download. When I was part of the Yahoo! Geo Technologies team, we released a public download of the Yahoo! WOEID data set, under the CC BY 3.0 license, in 2009 at Where 2.0. More about that license in a moment.

As Yahoo! continues to undergo change under the leadership of Marissa Meyer, the current data file and all earlier versions were taken offline. Visit the GeoPlanet Data page on Yahoo's Developer Network site and instead of a set of download links, you see "We are currently making the data non-downloadable while we determine a better way to surface the data as a part of the service.".

I take a lot of photos, most of which end up on my Flickr photo stream. While some of them are taken with a proper camera  (though some would say that my Lumix FX12 isn't a proper camera), most of them are taken with my iPhone, which doesn't take great pictures but takes pictures which are good enough and with the added bonus that I have it on me almost all of the time.

My photos all used to be publicly accessible and with an all rights reserved copyright on them but then I lost my Flickr innocence, which was a bad thing at the time and switched all of my photos to friends and family visibility. About a week later, when I'd calmed down a bit, I went through all of my photo sets; photos of my family and of home stayed out of the public eye and stayed all rights reserved. But everything else, I opened up and changed the license to some rights reserved using the Creative Commons Attribution Share-Alike license.
