There is a regular over there, BoBigRed that has like 3,000 posts and people are still telling him to f*** himself when he makes a post.
Bo is very highly thought of -- a lot of people think he's the best guest fan on there. He does a weekly write-up on college football that is very appreciated. I don't recall anyone telling him to f off -- if you say it happened I'm sure it did, but it's certainly not a regular occurrence.
You have to understand, shaggy started as a spin-off from hornfans.com, which is the most overmoderated site on the web. You can't say ANYTHING negative about the team or any player there, even when it's true, or they'll ban you for a few days. The moderators are jerks and they're wayyyyy over the top in how they handle everything and they get into personal arguments with posters then hold a grudge forever, etc. So some computer types got tired of it and started shaggy as an alternative that would not be moderated at all, and several hundred people immediately defected and went over to the shag. Now it's moderated, because it has to be, but very, very loosely moderated, which means people can say just about anything they want. And yes, some people abuse that.
So, yeah, you'll have to filter through a lot of foul language, but no one is going to tell you to f off just for being a fan of another school. An ISU guy asked about tailgating in Austin and he's gotten a ton of helpful, cordial advice. You kinda get back what you put out there on shaggybevo. The people that get told off are usually not completely innocent themselves.
Anyway, if you can ignore the tools, there really is a lot of very knowledgeable football talk on there. You just have to figure out whose posts to read and whose to ignore. And it's not a bunch of sunshine pumping like you'll find on OB and HF. Shaggy has threads with pictorial breakdowns of why our offense is so hideous and how Blake Gideon is always out of position. We might be a bunch of jerks, but at least we're realistic jerks!
