You can argue that it's cheating or you can argue that there's a vague degree of ecological-friendliness but sometimes you just end up recycling and repurposing a conference talk deck for more than one conference. So it was with my keynote at GeoCommunity in Nottingham last month and my keynote at the Location Business Summit in San Jose. One deck, two audiences. As it turns out, taking this approach can yield unexpected benefits.

Firstly there's the UK audience at GeoCommunity, the Association For Geographic Information's annual get-together and all round geo shindig. GeoCommunity is probably the closest the UK has to California's Where 2.0, but with a very different audience and a very different accent. The AGI still draws the bulk of its membership from the GIS heartlands of the GI community, although in recent years the association has dramatically expanded its reach into the web, mobile and neogeography domains.

The Location Business Summit, on the other hand is firstly in San Jose in the heart of Silicon Valley and secondly has a very pronounced American accent and draws the bulk of the audience from the Bay Area where web and mobile, both from a developer and from a business perspective, hold sway.

One deck, two audiences.

Last Friday I ventured north to Nottingham, along with Ed Parsons, Steven Feldman and Muki Haklay to attend the one day Supporting the Contextual Footprint event run by the Horizon Digital Economy Research institute at the University of Nottingham. Along the way I discovered a manner of tracking my journey that I'd hadn't previously considered, but that's covered in a previous blog post.

The focus of the Horizon event was to discuss the infrastructure needed to support location in its role as a key context and to identify any research theme that came out of the discussions; a classic case of the ill defined and fuzzy interface between the commercial world and that of academia.

This is a post about location (for a change); but it doesn't have to be about location as it's all about mistaking a vital element for the end game itself. I should explain.

I recently got contacted by a gentleman in the US who was looking to register a lot of domain names, in a manner which recalled the rush to buy domain names in order to make a profit as the dot com boom rushed headlong to become the dot bomb bust and which resulted in the unlovely pass-time of domain squatting.

After seeing a lot of mention of location, location based services and location based mobile services in the media, the position of location based services on Gartner's most recent hype curve and seeing a lot of acquisition activity in the location space, he was looking to register domain names with LBS in them.

I recently wrote about echoecho, an SMS based location sharing service and rather dismissed it as another PlayTxt or DodgeBall, both of which are now shuttered, and argued that EchoEcho fails my Theory of Stuff.

Nick Bicanic, the CEO of Purpose Wireless, the company behind echoecho was good enough to look me up and drop me a long email commenting on my blog post and -- very politely -- pointed out that I might want to revisit my opinion of the service. An edited version of that email to me formed the basis of his latest blog post on the topic of location as a context.

Like a lot of people, I get most of the information I use, both personally and professionally, from the web; from RSS feeds, from keyword search alerts and from Twitter. The genesis of my recent Theory of Stuff slowly accumulated out of this mishmash of feeds, alerts and status updates.

Firstly I read about EchoEcho, a new location based service which promises all manner of good stuff by showing you where your friends are regardless of which location based service they currently use. Let's leave aside for one moment that the service independence of this app seems to be based around the concept of getting all your friends to use EchoEcho and then consistently getting them to report their location. Let's look at something far more fundamental than that, the strong sense of location deja vu harking back over two years ago. Haven't we been here before?
