Web 2.0 - account managment

I decided to create new accounts in bloglines, delicious, flickr, to match the Smilin' Librarian moniker. This meant I had to create a new email account, this time with Yahoo! It's all done now, although there's little content within each of them yet. I have yet to get the digital photos off the camera and into flickr! Watch this space!
Even just creating these few accounts I did rather experience the username/password overload that can easily overtake one with Web2.0 accounts, in addition to all those other pieces of logon/security information one accumulates both at home and at work.
Several of my colleagues are interested in what I've been talking about, so I didn't want my holiday snaps appearing during any demos!
