I do think that a .com is better than a .ly because we've grown sick of "cute" domain names, but we've (at least I've) mostly grown sick of non .com's because they often tack on top-level domains to create nonsensical English words (see: my HN username, chosen for lack of creativity). The strange thing about Optimizely is that they've gone for one of these nonsensical, top-level-domain-inspired English words, but not the domain associated with it; to me, it seems like the worst of both worlds (note: I don't personally care that much; I think the site and product looks great, it was just an interesting point I noticed). More importantly, I honestly think people would hear about Optimizely, and then get frustrated or confused when optimize.ly redirects to bit.ly (though I guess people who aren't then willing to do a quick google search might not be their target audience).
