I’ve been playing with a number of location-based web services recently, thanks in large part to the joy that is Fire Eagle, and the most interesting so far has to be Rummble. As well as locating people you know it allows users to add places of interest, tag them and rate them on a sliding scale. And not just pubs, clubs and shops, either, but any sort of places. I’ve added mediaeval buildings of interest, for example.
The real fun comes when you’ve added enough places for Rummble to be able to figure out the kind of thing you’re interested in. At that point, it start colour-coding places depending on whether it thinks you’ll like them or not. Find people whose taste you trust and the system takes their opinions into account, too.
I should point out that Rummble is still under development but I think it shows real promise. The interface is, perhaps, a little cluttered but that’s fixable and it’s far from unusable. If this kind of thing floats your boat, give it a try. Oh, and try not to worry about the privacy issues – you don’t have to be too specific about where you are, you can set privacy options on the site and, of course, you can always lie about where you are.
