Does vote(up/down) in MSEmeta affect reputation in MSE or the converse.

Question

Does the vote up and vote down in MSEmeta affect the reputation in MSE or the converse. Also why is there a difference between the reputation of MSEmeta and MSE. They are fairly close in my case, just wondering.

Answer 1

Voting on meta.math.SE does not affect reputation anywhere.

(However, the badges you gain on meta.math.SE are separate from your badges on math.SE.)

Your meta.math.SE reputation is a copy of your math.SE reputation, though sometimes it takes a few hours to update to the latest value. This is how all meta.____.SE sites work, except for meta.stackoverflow.

See this meta.stackoverflow post.

Answer 2

Meta has no impact on your main reputation. Instead, your meta rep is exactly your main rep, with any discrepancy caused only by a small latency between rep changes on main being updated to your meta account.
