However, simply because it’s different, I’ll try it out with some of my PHP applications; hopefully it doesn’t go offline at any point.

I like what you’ve done: simple service + API + optional pointer.
Two things I want to give as feedback:

a) The pointer cannot start with a number. Too bad!

b) The bookmarklet does not support adding the pointer.
I tried by simply appending &pointer=blah to the URL, and it returned a shortened URL without the pointer.
Would be nice if you can fix that.

Keep up the good work on your blog.
Just stumbled on it today, adding RSS to my Google Reader.
Really like your jQuery stuff and your style.
