I guess this is an oversight. That link is probably best deleted, or maybe changed to:
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
The fact that it pointed to SE which isn't really a Q&A site was an oversight, but upon review the link itself is redundant since there is always a link in the header bar. Removed.
Q&A stands for Questions and Answers. The link directs you to the lobby hub of Stack Exchange, built on Q&A.
The Stack Exchange homepage displays the so-hot-right-now questions which have answers.
The oversight here is that chat itself is not enough of a black hole of despair.
