Yesterday, a new search engine launched, its name is Topsy. Topsy's tagline is "a search engine powered by tweets." So there you go.
If you look at the WebmasterWorld thread, all you will see is disappointed searchers. Here are some quotes:
Tried a search regarding furniture delivery and I got 7 out of 10 results from the same company/account and looked very spammy...
I don't like it. Very slow and bad results.
The creators should be fined for wasting bandwidth.
interesting. I topsied the name of my city, and thre top results were some public events coming soon, some sports scores, and where to get the lowest gas prices in town. Not relevant results like City Hall or Munipical News. These are things people are tweeting about.
I can see how this might be alluring... but I can also see how the results might turn many people off.
