grrrrr. apparently HN always strips single-quotes from links. There should be single-quote in the link in doesn't.

Here's a bit.ly link :-( http://bit.ly/9iQWn8

You could always URL encode it: http://www.quora.com/Why-doesn%27t-Quora-use-PostgreSQL

That way everyone clicking on the link from the home page doesn't get taken to the 500 page.

Argh, that is really annoying though, and our servers really should be able to figure out that the two links, apostrophe or not, should lead to the same question. I'm a bit late to the game; was the original link up top unchanged?

Edit: should be fixed now.
