Library 2.0 & del.icio.us

I really like del.icio.us. Every time I'm reminded of this site, I realize how much I really like it. But I just don't use it very often and I'm not sure why. But I think a web-based bookmarking site is awesome and such a great idea.
I've been reading about the concept of Library 2.0 for a couple of years now. I think in general, I appreciate the concepts that Library 2.0 describes. I'm not sure how new some of these concepts really are, but I don't think it hurts to have them described as formal concept to encourage service and innovation.

Facebook, MySpace, Ning & other social stuff

I have been using Facebook for sometime now. Actually, using is not really accurate. Perhaps, I should say I occasionally get on Facebook. One of my younger sisters talked me into setting up account awhile ago, but I really only get on to see my younger siblings in their social element :). I haven't had much luck connecting with friends from the past, only current friends/family. I'm not as familiar with MySpace, so I will have to continue to play around to see which I might prefer. I do like the privacy settings on Facebook better though.
Ning was interesting. I like the idea of setting up a site specifically for a certain group. My family uses another social networking site where we have set up a site just for our family to post photos, video, write blog entries, chat, etc.

Rollyo and other stuff

So, I played around a bit with LinkedIn, Library Thing and Rollyo. I actually think my favorite was rollyo. I like the idea of customizable search engines. In a sense, it's creating a pathfinder of sorts for the internet on specific topics. I think it could be quite useful in library applications. I was not as impressed with LinkedIn, the concept is good, social networking for the working professional. But I'm not sure that I personally would use it all that much and when I tried to find colleagues from a past job, their search function did not work very well. Library Thing is a great concept and I've explored it in the past. It seems to expanding rapidly into many venues and applications, but I am using another site to keep track of books I've read.
