Web 2.0 Tools

OMG How many tools are out there? I actually realized that I am fairly up on some of the more popular (award winning) sites. Mainly through others' invites, not because I am up on things myself... I have however payed it forward and gotten people to join things like Facebook, set up iGoogle, join Twitter (yeah I took a little pushing...), set up stations on Pandora (and share stations). I guess I am not as far behind as I thought. Unfortunately, I have chosen a profession that has not fully embraced web-based applications (that I've come in contact with). Many cannot see beyond the risk factors. I really think an opportunity for greater real time collaboration is being overlooked, but who knows maybe I am a leader in the trend...
