Delicious

I like Delicious a lot - it's great to be able to access my bookmarks from anywhere! I use the Delicious app on my iPhone as well, which is really handy, especially for recipes when I'm in the grocery story and don't remember what goes into what I make.

I'd never used the option to see other users, so that was neat.

A great online shopping tip: search everyone's bookmarks for "shopping" or "valentine" or "jewelry" or whatever you're searching for - seeing what's popular and interesting out there can be handy when you're stuck for ideas.
