A summary I've seen frequently, but a very inaccurate one, unfortunately. Talk (formerly itT) was never particularly developer-oriented, but it was very much an enthusiast's forum, the population of pure end-users was nearly non-existent. It was a community of engaged users, not just developers.

I disagree, the focus on Talk has changed. The previous devices didn't do well in the maintsream market, and most of the traffic here came from engaged users. The N900 has much more mainstream appeal and with it it has brought with it a lot of pure end-users. They're not interested in sticking out for the long-term and they're not interested in contribution. Now, there's nothing wrong with that, but Talk has changed, it's not the same place it was a year ago.
