backtweets is awesome!
I don’t know how I missed it for so long, but http://backtweets.com is really awesome.
Why is it awesome? One of the biggest drawbacks of having short urls on twitter is that you can’t search for tweets referencing your domain. And just this week I was trying to see who mentioned this site on twitter, when I found their service. Very simple concept and very well done (note that this is not a paid post, I just really liked it).
This is the output when I searched for fseek.me:

One problem that I noticed is that some links were missing, but very few of them. I guess they monitor the twitter stream (for everyone), so missing a few tweets is expected.
