Do you find it annoying and insulting when someone starts a thread with typos in the title? I snort in contempt when I see a new thread started and the poster hasn't even bothered getting the spelling correct in the title, or starts the thread off with a post full of typos and crap grammar. I've found that the more stupid mistakes there are in the title of a thread and in the poster's initial post, the less interesting and worthy of reading is the thread. I'm not going to bother opening them anymore. Call me a grumpy pedant but I don't care.
(Actually I think I've done this once or twice myself so I'm probably a hypocrite, lol)
