I've only been using Foursquare for a week or two, so I thought I'd share what I've learned so far, for anyone who's never tried it! My thanks go to Lucy Waters for her patience and skillful camera work, by the way ...
Something I don't mention here is the integration with Twitter - the default settings mean that an automatic tweet is sent whenever you check in, get a badge, become Mayor, etc - which took me a few days to realise! Not wanting to deluge followers with my Foursquare antics, I've now turned these off. You just have to explore and play around a bit to find these things out.
If you're a seasoned user of Foursquare of any of these geo-location services/games please leave a comment and tell me about your experiences/impressions and what you think of them... or if you think it's all a load of rubbish, let's hear your reasons!
