Last week I wrote, as I mentioned, about the H1-B visas for foreign tech workers. One way of finding out whether your subject is controversial or not is, I guess, the numer of e-mail you receive from readers. Using that parameter, this must have been my most controversial article so far. One reader wondered why foreign farm workers won't be granted the same kind of visa and concluded "I guess MONEY talks." Well, I can't argue with that.
