More a meta post, or what Kuro5hin would have called MLP (meaningless link propagation), this post started out as a comment to one of my previous posts on the iOS location caching controversy but soon expanded way beyond a comment into a full blown post.

Firstly, let's get the conspiracy theory out of the way; this theory has been presented in a variety of ways but all of them seem to think that your iOS device is tracking your location and that the reason for this is some shadowy request from government or intelligence agencies. Perhaps the most eloquent case for this was on Frank Reiger's blog.

Now I love a good conspiracy theory as much as the next person and Frank’s blog post was a great read. But I have to take issue with the two main points he raises. Firstly there’s “if it was a bug then it would have been fixed … it hasn’t been fixed so it can’t be a bug and must therefore be deliberate“. Secondly there’s “not only has the bug not been fixed but the file even moved location without being fixed so it must be (even more) deliberate“.

It's time to put the Theory of Stuff out to pasture. It's had a good life. It's appeared in 5 of my talk decks (or so Spotlight tells me), in 3 of my blog posts and continues to generate hits on my blog (or so my analytics tells me).

When I tell people I'm going to talk about my theory, a Mexican wave of shoulder slumping passes through the room, coupled with a prolonged sigh from an audience who've just resigned themselves to a slow painful death over the coming minutes. Luckily things perk up when my introductory slide of Anne Elk (Miss) and her Theory appears but even so, it's time to quit whilst you're ahead.

But before I do ...

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?

Once again, this is not the post I set out to write. The one I set out to write was called "In Search of Location's Sweet Spot" and it's sitting in draft and not yet posted. That's because before I can submit that post I need to write this one as a warm up act. Just like Anne Elk (Miss), I have a theory. I call it my Theory of Stuff. I'm sure that other people, far more learned and erudite than I, have articulated such a theory but I've yet to come across any evidence for this and for now at least, it remains mine and it contains three buckets, looking something like this:
