SecondBrain is a personal aggregator that doesn’t just aim to collect all your online content in one place – it helps you organize it. It’s a bit del.icio.us, a bit FriendFeed and a bit Onaswarm, all rolled into one, with a new twist you’re not going to find anywhere else.

You can import content from Twitter, del.icio.us, Blogger, Wordpress, Digg and StumbleUpon, and that’s less than half the list. You can also get your content into SecondBrain by adding links directly to the site. With most other aggregators or social bookmarking sites, that’s all you have to do. This is where SecondBrain gets interesting, because it allows you to organize your content into collections and share it with your people who follow your updates. SecondBrain’s latest feature gives all users 1GB free storage.

It’s still lacking certain features, the most significant one being the inability to export your links, but we’ve been told that’s in the works.

SecondBrain appeals to that obsessive compulsive need to keep all your online content neatly tagged and filed away. And what better way to do this than with a service that allows you to share it with other like-minded people?
