So, evidently this little service tool has gotten some posting coverage, in TUAW and a few other places. Yipe! So, here's a quick second release.
I've added a new 'Shrink URL to Clipboard' service as requested, so that you can still shrink a URL in a non-editable text-field; it just puts the result on the clipboard instead of replacing the original.

I've repackaged it as a simple drag-and-drop as was suggested; you can drop it into ~/Library/Services to have it just for one user, or into /Library/Services to have it system-wide. To uninstall the old version, just delete /System/Library/Services/TinyURL.service; a restart /is/ still required, but that's a limitation of Apple's system-service stuff... I can't really get around it.
