I never know whether to upvote something like this or not. Perhaps I should, because I thought it was interesting and relevant enough to submit it myself:<p><a href="http://news.ycombinator.com/item?id=3102321" rel="nofollow">http://news.ycombinator.com/item?id=3102321</a><p>But then again, perhaps I shouldn't, because no one upvoted it when I submitted it, so the concensus of the HN community is that it doesn't belong.
