Perhaps not so much pedantic but will often misconstrue things you've said or imply you said something you clearly hadn't. It's often worse on a long thread and someone will refer to something you'd said a long way up thread, and just as in a conversation in real life you might have forgotten what you'd said. Time is then taken up trawling back through your comments to something you'd said but has been taken out of context. It's fair enough when they have a valid point but it can get tedious when you have to keep going on the defensive about something you hadn't said. Sometimes you feel like you're being grilled by the gestapo.
