I have things in open browser tabs (Safari and Firefox on multiple computers), Safari Bookmarks/Reading List, Hacker News favorites/upvotes, pinboard.in, Digg Reader favorite/saved, Reddit saved/upvoted, Github watched/starred and plenty of others that I am forgetting. As you can see, I have absolutely no discipline at all. A lot of these topics are obscure and not easily googleable and I waste a lot of time trying to find things. It would be nice to have an aggregator for all of my saved content.
