It would be awesome if I had a secondary system for quickly accessing information I’ve previously come across. A search engine for information I’ve consumed.

I’ve been thinking about this a while back. I employ a couple of tools to aid me remembering the stuff I’ve come across on the net (and if you’re anything like me, you’ve felt the necessity for this, as well.) I don’t know the solution for this problem though, as the content I consume doesn’t move through one channel anymore, but rather a lot. And (I really need to work on this!) oftentimes I only realize that I should have saved something for posterity when it’s too late, when I need a certain bit of information but can’t find it anymore.

Tools like Pinboard only help insofar as I have to remember to commit sites/posts I’ve read to the service, which leads to the aforementioned problem of realizing I haven’t pushed stuff there when I need it. Often, the instances of Tweetnest and ThinkUp I’ve got running on my server save the day, because they automatically (and passively) capture what I share, predominantly via Twitter.

However, I wish there was a tool to passively store the content I read over a wide range of services (if annotations were permitted, that would be awesome) and make it searchable later.

Can someone build that, please?
