It came to me via a Tweet. That Kenneth, always in the know.
So, tr.im is dead. Which is unfortunate, because I wrote my wee-little WordPress Tweet plugin on the back of tr.im (for URL shortening automation).
As luck would have it, “market leader” bit.ly has an API, too. Too bad you have to authenticate to use it – the tr.im implementation was way less strict.
And why is it that these URL shorteners can’t monetize? Just show an ad on the jump! Duh. They should have had an easier time of it than Twitter.
