Have just done the searches on Technorati for Learning 2.0. Using the keyword search function we found different results for blog posts and tags. There were more results for tags, about 750, than for blog posts, about 550.

Technorati is a good website to find the 100 most popular blogs, the most popular blog subjects and just fun to have a look around at other people's blogs. You could spend a lot of time looking at the website and lots of blogs!

I have just been reading about Tags and Bookmarking using the site Del.icio.us. Tags are a way to organise your work or blogs in a free-form method of catagorising. Other users can add their comments and links to this. It is helpful when you run multiple blogs or different sorts of blogs/podcasts such as a video blog (vblog), written blog or audio blog.

With regard to using bookmarking as research assistance, I think it would need to be less free-form or more controlled so that people do not create unsuitable catagorises. Bookmarking is better suited to be used as a tool to let you access blogs anywere.
