Week 6 :Tagging , Del.icio.us and Technorati

I have used Del.icio.us and Technorati before and while I have found them interesting, I haven't embraced either with any great enthusiasm. I can see where Del.icio.us can be useful for researchers if they wanted to follow the trail and find additional serches but when you are short of time you haven't got a lot of time for exploring. Technorati is a useful tool when you need to search blogs and the like but again I haven't had a great need to do that
