With the Yahoo! Geo Technologies sponsored, London #geomob meetup coming up this week, this weekend I took a look at how many companies were actively using location within London. No easy task. After much web searching this weekend I took a trawl through those companies tagged as being in London in CrunchBase, the database of tech companies that TechCrunch operates.

Not strictly scientific but then again this is more about gauging a trend than being strictly empirical.
