I saw many changes of user interface on meta site . I would like to know what is meta user tab (check below image) on my profile page?
Am I getting new account with reputations as SO account (link) ?
Meta Stack Exchange is a question and answer site for meta-discussion of the Stack Exchange family of Q&A websites. It only takes a minute to sign up.Sign up to join this community
The account linked in the question is for Meta Stack Overflow. This is a new per-site Meta associated with Stack Overflow.
This site is used to ask the questions related to suggestion, bugs, and doubts about Stack Overflow.
Before this Meta Stack Overflow was the Meta site for the entire Stack Exchange network. This has been migrated to Meta Stack Exchange (this site). Questions related to SO should be only there.
This is reason you feel changes on the Meta site.
