Do you find people sarcastic online?

I have been accused of sarcasm, probably quite rightly! They say it is a poor form of wit but black humour of today thrives on it. Unfortunatly, many people here seem to have such a poor sense of humour that you have to put haha's or LOL everywhere to give them forewarning that they are supposed to find the comment amusing or at least ironic.

I think there are a lot of people who can be sarcastic online. The funny thing is, most of these people don't even know or aren't aware that they already sound sarcastic! I came across someone over the net a few days ago and I was so turned off by the way he "chatted". So I told him and he said sorry because he thought that he was just being himself and that he didn't mean anything bad by what he said and by how he said it.
