Nice of you! But I would say a list of logical fallacies in the whole does not seem relevant to most posts on this forum because, again, they seem to involve no real attempt to make an argument. More often it's some kind of noninformational exchange.
A compelling argument is one that anticipates attempt to refute it. IMHO, very little on this forum qualifies as argument in that regard. At the risk of overgeneralizing I'd say that most posts here are statements of opinion or belief and do not have the structure of argument at all.
In communication theory, there is a basic principle that interactions are purposeful, and that the purpose is apparent from the content of the communication. The fact that most posts here involve no real attempt to make an argument must make some sense. I suspect it makes very good sense for someone who is short on time or not sufficiently interested in the subject matter to actually put something coherent together.
Another possibility: Lack of argument is also potentially self-protective. If you feel like you can't win an argument, just don't venture one and then you can't be blown out of the water.
