@codinghorror: Some thought you were responsible for the limit. @sam explained that you were not, in one of the lounge threads. I think there is a general understanding among regulars at this point that the limit is set by BB staff, not you or Discourse.
As far as starting a meta topic, there have been several as you know. No one seems to be listening though, and there is never a reason given why there needs to be a like limit. Go through any of the past discussions you quoted, and you won’t find an actual reason given. Which brings me to this:
This is why there was no meta topic.
@JLW: I think it would be a good idea to listen to your user base. I expect though, that when I wake up tomorrow, this comment if not the whole topic will be gone. I really just wanted to respond to @codinghorror, but closing out the topic a quarter of an hour after it was opened didn’t really give me a chance.
