I'll bite (I wrote this post). I actually mentioned VisualWebsiteOptimizer at the bottom of the Optimizely post, but no, I haven't done a full profile on it. If the founder happens to read this, I'd be happy to check out the site — make sure to emphasize how you're different/better than the competition. I'd also recommend waiting a week or two to reach out, otherwise the post will be a little bit "me too".
As for why they may have been passed over in the first place, I don't have a definitive answer, but a few things come to mind. First, the name sounds off alarm bells in my head (or at least, makes it sound mediocre). Given the dearth of good, brief domain names I know this isn't fair, but most sites we see that are 3+ words strung together in a non-clever way are terrible.
Also, I notice that the latest email I have from the founder was sent at 3:40AM on a Sunday (he's out in India, so that would probably explain it). If you're going to send a pitch, try doing it on a Wed-Fri, around noon or afternoon. The news cycle tends to slow down then (and I'm still at my desk), though there's no set rule.
