Shak, if you really want to determine the frequency of posting activity, you don't really have to start a poll. A poll is less accurate than taking a random sampling of a given number of specific posters, checking their public profiles, and just doing the math. With the amount of live data available in here, the statistical calculation is quite elementary, my dear chap. In fact, with a poll, you are depending on our posters' memories, and these can be highly unreliable.
