If you have any particular powers over Google and Microsoft... :-)

As mentioned, I can and do use a different URL shortener for now, but it is
a UI element right there on the home page that will lead to people sending
around broken links. That can't be good.

If geohashes or some other system can be implemented - tinyurl, bit.ly etc.
doesn't seem to use punctuation marks - that would be great.
