This is a really cool web site! I had heard about it before, but hadn't taken the time to check it out... Let me try to explain it.http://del.icio.us/
(beside being a pretty cool URL), is a site that you register for, and then use it to store all of your favorite web sites. It's sort of like a centralized spot for all of your favorites & bookmarks. You can add a few quick buttons to your browser, one for 'post to del.icio.us', one for 'my del.icio.us'.
For each link to add, you can add a series of tags, or keywords, then you can also find other sites that other users have tagged with the same keywords.
You can also add your friends to your network, and surf through their URL's as well, also share your favorites, or post your favorites to your friends.
My del.icio.us account name is 'johnwaltca'
, so check it out, and add me to your network!
