I've seen Tomcos once or twice, and he seems like a nice enough guy. I would probably wait a bit and see if he's still on regularly over the next month or so, as I haven't seen enough of him to be able to make a proper judgement - but what I have seen has been positive (but it was over the span of 30 mins to an hour).
Maybe some others have seen more of him? I'm never really on at night so we might just not cross paths much.
