All of my reputation from Unix SE just appeared as 'new' to me on my meta profile. I have visited meta before (and it didn't display it all as new before). Is this a bug, or is it intended?
IIRC there's some kind of obscure bug where the computation leading to that number mixes meta rep and main site rep. Something like computing the main site rep gained since the last time you viewed your rep through the rep tab on the meta site. This may in fact be a feature, because meta rep is not supposed to be added up.
