I've found multiple instances of text in more or less official places containing general English problems (spelling, grammar). I'm assuming for the time being it isn't due to outright lack of fluency in English, and so that leads me to think that they just aren't putting in the [little] extra effort to proofread before publishing. It's not that big a deal, but I think it would help for them to look more polished as far as official text goes.
