Writing novels for posts is overrated. I immensely appreciate it when someone writes posts that are readable and concise. It's an awesome skill to have.
I still get what you mean though, about feeling inept compared to these supersmart typoCers because I have little capacity to read through the novel-length posts and I don't have enough information contained in my head to write a novel-length post if I wanted to. But some of the long posts that I try to read end up being like the same stuff that someone else summed up in like two sentences (so perhaps I'm not missing a whole lot), and I'm sure if I dedicate more of my time to reading stuff then the information will stick long enough in my head eventually.
