Firstly, I don't really see the point here. Currently, it's basically a game that asks "Which tweet has a missing word?" There's no obvious reason behind why I would want to play it, though. I will assume by gaining "score" my tweets will show up on the site for others to "guess" about. However, as I was playing, I wasn't reading the tweets for comprehension, just to determine which was more likely to contain the (arbitrary) "missing word" and I certainly didn't click on any links (well, not that they were clickable). This basically nullifies any banner exchange benefit. Secondly, the method you use to Captcha, i.e. missing words, is way too arbitrary and prone to wrong guesses. Take the following example: http://img.skitch.com/20081231-cexmqnxetfktd6ybbdfei8dpgp.png http://img.skitch.com/20081231-cexmqnxetfktd6ybbdfei8dpgp.pn... The first tweet was just ".net" which I presumed was missing a URL at the very least. The second wasn't even English, if it was a language at all. The other huge issue with this is the fact that, in general, tweets are going to be missing words because of the character limitation. I got a couple wrong simply because both tweets were missing words that would form a complete sentence, but only one of them was missing the word you wanted me to notice. Basically, aside from some sort of novelty, I see no use for this service. Perhaps I'm missing something.
