I just noticed that my rep on Meta Programmers is the same (currently 3898) as it is on Programmers. This is surely a bug, unless there's been a recent change to combine rep on meta sites with the main sites.
I could've sworn we've fielded this question before, but at any rate, this is not a bug: every child meta except for Meta Stack Overflow pegs its users' reputation to the corresponding main site user. It's been like that since Stack Exchange 2.0 launched.
From the Meta FAQ:
Reputation here is entirely derived from the main website; your reputation is the same here as it is there, synchronized hourly. Votes here do not affect your reputation in any way. However, you can earn unique badges here on the meta site.
