You called him an asshole in November. Its almost February. That thread was unpleasant from the get go.
I read a number of his posts and the discussions that followed. I could not find one post that was complimentary to his initial idea, or that seemed to go smoothly. He could be correct that he wasn't having any fun on AH. The posts I looked at from him didn't seem like much fun.
I have been on the forum about the same amount of time. I have been enjoying most of the posts and the discussions that follow. Not all of them mind you, but the overwhelming majority. I don't know what the formula for success on AH is. There are a lot of opinions that are dearly held in this hobby it would appear. There are also a lot of folks that "lack da social skills" (Waterboy, 1998).
Finding a way to ask questions isn't too hard for a newb. Finding a way to contribute and author posts or put forward ideas is a lot trickier than one might think. I am gratified at the depth of the responses I have received when I ask a question. I am sometimes mortified by the grief you can get for posting an opinion, idea or tidbit that runs just the least bit counter to an experts opinion.
I can't say whether the OP was ever meant to be on AH. AH attracts and holds a certain type of viewpoint.
There are plenty of forums that are almost "content free", and mostly consistent of opinion, hyperbole and adjectives. Some folks may just enjoy that approach better.
