Damned if I can read Theymos's mind, but I don't think it's got anything to do with the popularity of the Greek board or the language--he just hasn't tapped any new merit sources for any section in quite some time (that I know of, and I could be wrong).  And I don't know about anybody else, but I get the feeling that if the merit system is going to continue to be a thing, Theymos really really should at least consider adding a few new merit sources.  Older ones who've been doing it for years might be drained of enthusiasm, and some have dropped out for various reasons.  Looking at the merit stats, it appears that some of the big merit senders have been sending less (but I'm cross-eyed, so double check me on that)--but in any case there's going to be some attrition over time.  If inactive/burned out sources aren't replaced....well, this forum could go flying sideways at light speed into a shitposting tar pit.

Kind of how it was prior to Jan. 2018, you know?  Who the hell wants that?
