This is a Twitter tool I built for bookmarking tweets that I find interesting. If I don't have time to read something I just tweet the link to my @laterz account and it stores it for me for later. Then I can go back and read it when I have time. Typically it just stores the tweet for a few days.
This is sort of a "TV Guide" for web videos. It allows me to quickly find web shows/podcasts that I'm interested in. We have a computer hooked up to our television and this makes navigating around a lot easier.
