This question already has an answer here:
I confess, I didn't jump on the Stackoverflow bandwagon when everyone else did. I've recently signed up and I have a reputation of 176 on stackoverflow.com. To my surprise, I now find that I need 20 to be able to participate in Chat. Is this 20 regarding meta.stackoverflow.com? I find it odd that when signing up it detects my Stackoverflow account and associated me yet ignores reputation.
What happens if I have absolutely zero interest in meta? I understood the chat is irrelevant of meta itself or was I wrong?
