Project Play 8 - addendum

The population of libraries will increase exponentially with delicious.net, Library Thing, blogging, RSS feeds - well, the whole Web 2.0 concept. I can see where a virtual library can be created with postings just on Gusty Spence. It's like sub-Internet reality. My problem is that I still recall my Reference instructor in Library School giving us the tolls for evaluating sources. I am not confident that many postings are reliable, authoritative, timely, purpose, content, etc. Wikis disturb me....they look official, but I am hesitant to use them when answering reference questions.
