Perception often clouds numbers when this subject comes up, here is the search result by name for number of posts on the RPG board for the last month. Regrettably there's no quick way to get word count, filter out participation in other RPGboard threads, or set the search to specific dates.

Bergioyn - 7
Darth Katie - 61
Fistofpainx - 13
Fox and ravens - 55
Isaac - 77
Kronin - 54
Ranagrande - 24
White Flame - 25

That's fairly normal breakdown, barring the real low ones. It's a little hard, between RBIRL, skipped or modded games, and death in game to really compare posting numbers easily, but as an example, at 77 over a month I'm at 2.6 messages a day, with a little over 180 days to spread the 479 posts I have thus far ~2.5 posts per day, with my only major period silence being after my NK in DK's game. Katie herself comes up second at 2 posts a day avg and actually beats me out at 609 messages on the RPGboard or about 3 a day, though I imagine I still edge her out on word count since I've never met a run-on sentence I didn't like or bypassed a dead horse that needed a beating. Kronin comes in third at 412. FT scores in at 334, exactly tying Fox at 334. Gher at 226, and so on, with the numbers meaning less after that with some people skipping a game or dying early. It's worth noting that everyone on that list above Gher also have been active participants in other games on the board, whereas he hasn't joined any of those and probably explaining the current differential.

Just looking at our losest three posters currently - no point including you since you've been RBIRL for the last couple weeks and skipped games.

Bergioyn - 7 this month, 154 on the board
fistofpainx - 13 this month, 188 on the board
ranagrande - 24 this month, 145 on the board

So really only Bergioyn stands out, fist has been less talkative than his norm, but not by a whole lot and he really hasn't been involved in much going on, ranagrande posted a bit more than they relatively speaking but was also under accusation. Both have a history of quietness but also tend to reply quickly when addressed and the latter quality is fairly important. They obviously do need to be talking more, and definitely at greater length, there's literally a correlation post count and word count per post, with the lower poster also posting shorter messages and that list of the top being rather long-winded, so that even my posting 11 times more frequently than Bergioyn doesn't really tell the whole tale, since my average post has more length than all his postings combined, and this of course needs to be addressed - though arguably by getting me to talk less. So I don't mind the insistence that many players are showing to turn the spotlight on are less talkative players, I just want to make sure everyone has an objective list of activity since so far people have seemed to have a skew on this, i.e. you mentioned fist and ranagrande as inactive but not bergioyn, a bit back someone cited bergioyn and ranagrande but not fist, etc. Bergioyn's is really the only person being abnormally or critically quiet, since everyone else has been posting every other day to twice a day on average, which is a decent range compared to previous games.
