Yesterday I cleaned my del.icio.us and I got lot of surprises. Some of them was a "How To" teaching how to use advanced search in gmail. When I saw it I thought: "What hell is it doing here?", sincerely, I don't know why I added this web site in my del.icio.us.
Others, like http://www.dbexperts.com.br/replicacao/intro or http://www.onlamp.com/pub/a/onlamp/..., show a subject that I needed months ago but now it's not important to me anymore: database replication.
I know that it seems a bit "crazy", like clean my bookmarks, but it's annoying seek for a bookmark, even if you use the del.icio.us firefox add-on, and find lot of trash a.k.a. "websites that you've never used or you won't use".
