I joined for Bills news and discussion, so in that respect, TSW is why I'm here. In addition to news, I like to read other peoples' takes on games, players, coaches, etc. I'm not as well-versed on the Xs and Os as those of you who watch the All-22 and stuff, so I've learned a lot from that. Sometimes, it gives me things to look for in games.
On the other hand, I probably post more in OTW. I'll share an opinion or two on TSW, but I'm more of a reader there. In OTW I'm more of a participant.
