Last year around this time I posted a similar fanpost:
2018 comment tracker
So we could see how many comments we had in 2018.
My last comment in 2017 was comment #43,145. As of today (12/26), I have 50,085 so just under 7k for the year (I'll probably get there before the 31st).
Check to see if you commented last year (oofda did! freezeface did! ChiVikesFan, Gone Fishin', just_rob... and MORE!) and calculate your 2018 comment count.
FUN!
