I noticed on del.icio.us that there's no actual way for someone to connect with someone else like on other social-networking websites. Then again, del.icio.us is more of a bookmarking website than asocial-networking website.
BUT... if one decides to go deeper into his/her del.icio.us settings, they wil finally realise that there's a way to connect with people and share the same interest as other people.
Basically, it's simple, that is if you're good (not an expert) with html, you got an account with del.icio.us and also you own a blog, you can simply go to del.icio.us's setting and create either a network badge, a link roll or a tag roll, which you can set or your blog, and once it is set, you will get to know exactly with whom you're dealing with.
This can create lots and lots on connects depending on your interests.
