Short answer? In my completely subjective opinion, no. Long answer? How exactly are we going to quantify or define the line where which forum roleplaying has died out? Forum activity on dedicated roleplaying boards? The post frequency of a roleplaying board? The number of members? The average word count of posts? Forum roleplaying isn't slowing down. It's changing and is large as it has ever been. To constrict your view entirely to experience on RPGO or on the other sites mentioned in this thread is simply naive. There are hundreds of other role-playing forums, roleplaying subforums and let's not even get into the other mediums that have arisen over the years that have called themselves 'forums'. I've seen play-by-post roleplaying [i]sub-forums[/i] that dwarf RPGO in size and are still active as they have ever been. So, to put it shortly, no. Forum roleplaying has not slowed down. It's just changed just as the world and its mediums of communication have.
