Impressive List Of Web 2.0 Lists

I was speaking to someone known to me last week and I was stumped when he asked me to point to one source where all info about Web 2.0 applications and reviews can be found - his point is, in the Web 2.0 world, its a natural expectation to find such information over the web. Richard MacManus comes closer to meeting the expectation with this impressive list of web2.0 lists . Indeed well researched - as he says, for somebody trying to analyse the Web 2.0 movement, he /she shall have to go much deeper than the high level product data and digg out/ synthesise findings into practical insights, recommendations, knowledge, etc..
