If you're like me, you spend <em>hours</em> worrying about how popular EoFF is compared to other Final Fantasy message boards. I can hardly sleep at night.
vBulletin boards happily display how many users are currently logged in, right on the front page. Last night I wrote a little Ruby script that automatically runs every 15 minutes to record how many visitors are currently online at the top 20 or so (as reported by Google) Final Fantasy message boards. I ignored non-vBulletin boards (all of which are extremely small, from what I can tell) which leaves 17 MBs. Today when I got home from work I had a nice little pile of data waiting for me.
There are some caveats here of course; for example these numbers largely depend on the (I believe configurable) timeout after which vBulletin will consider a member no longer visiting; a longer timeout will inflate the numbers. However let's work under the assumption that all the MBs are using sane and comparable timeouts.
This is a chart of one day of data including lurkers:
Lurkers are probably skewing the results given how many of them are search engine spiders. So I separately plotted only the non-lurkers (i.e. only logged in real human members):
Now we can all rest easy.
