My main hobby is learning foreign languages and I have noticed that a very large proportion of people on language-learning sites happen to be programmers of one sort or another. Of course, this may just reflect a tendency of programmers to be aware of and use the technology available to pursue their other interests, and thus be overrepresented on such sites, rather than an affinity between interest and ability in computer languages and natural ones...not to mention the fact that programmers coming from a non-English background have a very strong incentive to improve at least their English.
