The subject of tagging is one I have been wrestling with recently. I am leaning to thought that "more is more". That is when I use service such as http://del.icio.us/lumpy, I try and use as many tags as possible and copy as many of those already used. After all is the objective not to have others find it?

If I am thinking newsfeeds and another thinks RSS, I must use both tags for both of us to find it. I foresee search technology making this less of an issue in the future.

I do not sweat tagging much on my blogs. My personal blog is about as organized as the inside of a three year old's toybox. However, that was my first blog. Newer projects are now better structured in terms of catagories.
