“Why should I use del.icio.us?” is a question I got the other day. It seems that del.icio.us provides no search engine love as it blocks the bookmarks with nofollow tags, yet it is very valuable.
What del.icio.us is good for is exposure. Lots of people use del.icio.us to not only store their own bookmarks but find new and interesting websites. I know that sites like LifeHacker sometimes posts on what is popular in del.icio.us too. This then turns in to a very valuable link back to your site.
What you are really doing is trying to create buzz and visibility for an article or a site that you think is interesting. It’s not about
spamming link building for search engines.
