This was a little midnight web programming project of mine. Maybe there's another service like it, but I haven't found it yet. If you have any suggestions for additional shortcuts, send them over!
Well, I'm impressed. It worked without fuss for my, hardly known photography blog (photub). I thought maybe there was just a list of aliases, but that can't be the case... are you just relying on a common url pattern of search/?q=<query> or are you actually a reader of my blog?
Interesting, didn't know about that, but it looks cool. It looks like it just uses a list of aliases though, while I default to treating the keyword as the domain name itself and extracting the form from the HTML of the page.
