"I also think there's tremendous value in creating a dedicated music graph (as opposed to a social network that also has music); it's in your best interest to follow (or unfollow!) someone regardless of whether you're strangers or best friends. It's all about the music you're going to get from that person in your playlist of jams." Yep, this – which is the thing I always try to explain about TIMJ. I don't follow the list of people I follow everywhere else; I follow people who make my playlist of music better/worse. It means I discover all manner of new music, but I hope nobody takes it personally. (About the worst thing you can do on TIMJ is just import all your Twitter contacts and not add anyone else ever).

"Jones said how most open city games tend to come with about 100 licensed tracks, but that they realised that most players would far rather listen to their own mp3 collection. But this is an online game. So they’ve done a deal with Last.FM to use their technology in such a brilliantly imaginative way. If you’re listening to a favourite track in your car, and drive past some other players, should they have the same track on their hard drive the game will find it, and they’ll hear it from your car as you go by. Should they not have it, the game will find a track that’s similar and play that instead." Just that quotation alone is remarkable, but it really does sound like APB is something special; let's just hope it's a success.

"…there are an awful lot of excellent reasons for ending a blog, and that many blogs which do end are by no means “failures”. Social media coverage in general should focus a lot less on the things people do or don’t “achieve” via these tools, and more on the fact that conversation, writing, collaboration and suchlike are pleasants thing to do in and of itself. Reclaim social media for the flaneurs, is I guess what I’m saying!" Tom Ewing is right.
