I like that this has the ability to be used as a prefix on a service's url. I don't need an extension.
I also like that this daemon (for lack of a better word), tries to keep its list of redirect targets fresh by pinging them. I have libredict[0] installed, but it is all but removed at this point. More often then not the instances I would be redirected to would respond with 4xx and 5xx errors. Not useful. :(
