I have just installed the Stack Exchange Android app, and have been creating accounts on different sites on Stack Exchange.
I noticed that from the main sites, I can reach a "meta site". What is this meta site?
Note: this question is about per-site meta, not Meta Stack Exchange which is covered aleady in How does Meta Stack Exchange work?.
Meta sites are for meta-discussion about their respective sites.
In other words - https://meta.askubuntu.com is for discussing the Ask Ubuntu site, community and such.
https://cs.meta.stackexchange.com/ is for discussing the Computer Science site, community and such.
Meta Stack Exchange acts as the meta site for the whole Stack Exchange network.
