Had to wait for the data to be ready, but according to my little spreadsheet o'Rep, the top 25 Rep people posted 7,384 times from May 1 through July 1.
From May 1 through July 1 over the past several years, we've had this many posts from that top 25:
2019 - 5,574
2018 - 6,140
2017 - 8,909
2016 - 6,474
2015 - 5,602
2014 - 8,390
The two outliers are 2014 and 2017 - Riley's first year and Frost's first year. So that generates a bit of excitement. The other years hover in a range between 5,000 & 6,000 posts, which is probably pretty normal for a message board during the main sport's off season.
So, honestly, there hasn't been a drop-off in posting year over year, and there has been above-average activity here this year compared to other years. Probably because there's a lot of election, virus and protest talk in P&R, and a lot of talk throughout the board about whether we'll even have a season.
Seems like the idea of a "ghost town" is probably more in your head,
