In case you were considering holding off the upgrade to Wordpress 3.3, take my advice, don't. For a free update I have no complaints.

So responsive in my use (Safari on a macbok pro), super fast updates, I've never seen performance on my website like this before!

If only there were some sort of simple plugin to cache links before they die to and archive the stuff you link to in case of failure . . . maybe there is, who knows?!
