August 18 Update - Help section has been updated!
Thanks to everyone who contributed! I've summarized the topics into the help section "What topics can I ask about here?".
August 12 Update – Final week! Cast your votes! Make your edits!
Changes to this Q/A seem to be tailing off. I'll add the on/off topics to the Help sections at the end of this week, including a link back to this Q for reference.
August 6 Update – 2nd inning PUSH!
Please vote, and best if you vote up/down on every topic (aka each answer here.)
I've styled some of the answers to make them easier to glance over from a "this is a list of topics" point-of-view.
This is a community wiki question; Please DO edit existing topics (aka answers here) to add example questions, clarification, etc.
July 31 – A call to arms!
Our site's Help section has a What topics can I ask about here? which currently provides only general guidance about what works well on Stack Exchange sites. I want to expand that section of our help to have specific examples of topics.
Please post answers containing topics you feel are, well, on-topic. That is to say one, specific topic in each answer. (...invent them, cull them from the main site, dredge them up from the Area51 proposal; whatever.)
Everyone is encouraged to up/down vote on as many of the answer/stopics as they wish. When we have what seems like some consensus, we'll harvest the top-voted answers/topics into the Help section.
Let's try to keep the list relatively short; We're hunting for the main topics we want to see.
