I was recently advised of the purpose of meta being:
for "more frivolous discussions"
Meta Stack Exchange is a special place for suggestions, bugs, support questions, and discussion about the Stack Exchange sites. It is the only place where more frivolous discussions are allowed. Meta is also harsh(er) to your feelings. That said, here are a few guidelines if you'd like to keep your sanity and reputation points.
Looking through the last 50+ questions, I cannot seem to find things that seem even slightly frivolous?
What does "more frivolous" mean in this case?
Please cite some examples of what would be considered acceptable "more frivolous" posts?
