I’m glad you found a use for your talent and it’s working out for you, but fandom doesn’t suck because your fandom didn’t recognise your fic-writing genius. All fandoms have issues and the bigger and more popular they get the more problems there are, and the harder it is to get noticed. But it sounds like you’re just better at writing about yourself and your job than writing fiction. It’s like blaming the editor at a SF&F magazine for rejecting your short story and saying they suck because you get lots of paid work for technical journals.
