what accounts for the upward trend beginning around March 2005?
Up until March 05 there were only a handful of regular posters (Nick, Hans, me, Kartograph, Cartomat and few others) and much of our time was spent sending out emails, requesting links, waiting for the site to show up in Google et cetera. Everyone was promoting in their own little way. All of this "work" started to pay off about that time. March 05 saw the coming of Martin who really boosted the quality and quantity of content at Cartotalk, as well as other heavy-weight contributors such as Frax, Dennis, Ecographic, Rob, Daveb, Mike, Rick Dey, Derek Tonn and Ben (who must have lurked for a few months before pouring-it-on!) plus several others. By the end of 05 there was enough substantial content and exposure to keep the site growing.Thus began the upward trend in March 05. The rest, as they say, is history! Thanks Nick for building such a great site.
My guess is that Martin is the most "verbose" poster and Hans is obviously the most active poster (12.36% of all forum posts!). Although Hans is probably a close second or possibly even first in the "verbose" category.
