Technorati, PLCMC Learning 2.0 and Del.icio.us

I had a browse around each of these web sites and read the comments on them. Found The Technorari one has a lot of different links and gossip which doesn't appeal to me. The PLCMC Learning 2.0 was interesting to read others progress and comments of encouragement. The Del.icio.us website is probably good for those who go on the internet and have favourite sites they visit and can bookmark them. If you are using tags, I don't see the difference to when I'm on a site, like google, like it and put it in my favourites to link to again.
