I'll bite on this one. Why exactly are you asking about the size limits?
As far as consistency, I get what you're saying: the truth is, we were still operating the literal free-for-all that Luuv has originally designed. There was no consistency because nothing existed to create that consistency - there weren't any written rules, there wasn't any organization or operational structure other than the folders themselves, and there wasn't nearly enough moderation to enforce "local rules" in a reliable way. We're in the process of putting things into place that make for more uniform action, but we're almost starting from scratch.
