When I go to a subreddit on Reddit, I see immediately in the sidebar what its scope is. When I go to stackexchange.com and click "Feedback always welcome", I get this place where I can ask questions.
Bug reports and feature proposals are not questions, and users should get reinforced that they are in the right place here.
The purpose of meta.stackexchange is explained on the help pages, but they are hard to reach: there is a miniature help button on the bottom of each page. Clicking help in the top bar shows Tour (which seems useless), Help Center (which discourages me further), and What's Meta?, a link to an essay about the purpose of meta.
What do you think?
