Just my two cents: If you're saving enough documents to where you need something like this, you're spending too much time bookmarking and not enough time actually making use of the knowledge contained in there.

I completely disagree, I keep running into the opposite problem: Having to retread ground on old projects because I didn't document what I did and forgot over time.

I even notice other people have this issue. I recently took over a project from a friend, but because he didn't document anything, I'm essentially starting from scratch.

I have never once regretted writing something down, but I constantly regret not writing something down.
