Perhaps a small point, but are you guys factoring in that forums in general seem to be on the decline as other social media formats are becoming more the norm? Add in mobile ease of access and forums are starting to become the “cassettes” of lore…
In Fm3 and Fm4 my group, which was huge, ran a spreadsheet with both euro and U.S. slots for series and no exaggeration, probably had 8+ regular series events a week.
Console migration happened, or didn’t happen, and the group was shattered. Some went to the One, some went to the new PS, some went to the old PS as it was cheaper, and some stayed on the 360. In fact, Fm4 is still easily the most active segment in our group. ( Oh and more migrated to PC as well, this seems to have been the final push to get some to do so.)
But, even through all that, our own forums are way down in activity.
