MLA CE - Social Bookmarking

I've used delicious before and found it cumbersome. If it had controlled vocabulary, then it might be more useful to me. I don't like scrolling through so many tags. And some people don't know how to spell. I also prefer to keep my life private. For work purposes, it might be helpful, but most faculty I know wouldn't want to mess with it. The main advantage I see is being able to access it from anywhere. The social aspect of it does nothing for me.
