Today’s weird netspeak, which seems to have suddenly just sprung up on news-links sites like digg (or, more likely, this is simply the first time I’ve noticed it):
RTFA, or "Read The Fucking Article." This is most commonly used to flame users that comment on a link without actually, well, reading the fucking article first. The implication is that this kind of behaviour occurs so often that people have taken to abbreviating their retort (in an effort, I suppose, to further confuse the already-clueless person they are speaking out against).
