tr.im is "discontinuing service". “However, all tr.im links will continue to redirect, and will do so until at least December 31, 2009.Your tweets with tr.im URLs in them will not be affected.”—these statements seem to contradict themselves. Will tr.im URLs in tweets stop working after December 31st or not? Any chance they could hand the domain over to the Internet Archive? At any rate, this is exactly why centralised URL shorteners are a harmful trend.
