None! Some have come close but in the end I was glad I decided not to ignore them. One has become someone who's threads I really enjoy.
I can see this sad old man sitting at his computer trying to convince all there words on his screen that he's rich and has all these toys and should apparently be listened to and I just take a moment to try and remember "don't be that guy".
The above post by ning really got me thinking "What am I doing to not be that guy". I can be argumentative to a point but I don't have to be absolutely right every time. Life is too short for that. I like to poke fun at people but it's really hard to get that to come out subtly in print.
In the end I decided while yes there are some on here that really have very few useful posts the overall wisdom and advice on here is worth a lot more than being upset with someone I don't agree with. Sometimes taking a day or so to cool off and think about how I want to reply does me a lot more good than immediately firing back. And some are not worth arguing with at all.
