I check "New Posts" frequently, easiest to catch spam like this.
My "main thread" varies, depending on what I play currently, with the exception of Brightridge: I spend/t so much time there that you could call it my basecamp by now
And while I am quite the RPG addict, I don't have the time to follow, let alone comment on, threads like RPG Reload. And I already played everything on the list that interests me, anyways
Update: almost forgot, I also have a lot of - more or less active - threads I follow. Just cleaned out the list to under 60 ... again.
And I read *a lot* of other stuff daily: several blogs, news, books, stories online, whathaveyou. Those want attention too, and "compete" with TA.
