i dunno... 11 of the top 14 links under the "Javascript" tag are about jquery (which has it's own tag). I suppose it's not a flaw in your algorithm, just not really very interesting results.
I know javascript and jQuery suffer from their popularity and utility I think in this analysis. There is also the issue of jQuery and javascript tags being used by people as synonyms. jQuery particularly is a 500 pound gorilla over all the dataset, it shows up everywhere. As I mentioned above there was a joke on SO at one point that the answer to nearly every question was jQuery with a link to the site. Apparently it wasn't a joke.
