I'm with you on the netspeak. It turns me off. And I'm mostly okay with poor spelling, as long as it's not every other word, And while I can excuse most grammatical errors, I do have a few personal pet peeves, such as people who don't know the difference between "their, there, they're" and "it's and its"-- shallow as it sounds, that seals my opinion in someone's intelligence in a heartbeat.
