Now that Steem has gotten off the ground, there is a use case that I would like to see implemented. The best part is that it can be done, right now, without any additional features! All we need is to agree on a standard as a community which I propose below. Most anyone that has done any amount of programming knows of stackoverflow.com. Nearly all of the world's textbooks on computer programming can be found in some form or another on Stackoverflow in the from of Question and Answer style posts.
For those that aren't familiar, go check it out. The site has expanded to various topics on the Stack Exchange network. A user has a question and others can give answers. Experts vote up correct answers, and the result is usually a simple question and best answer.
Why not use Steemit for this? I propose the use a new qa tag for all question and answer posts. For a particular topic use qa-topic. For example, if I had a programming question on javascript I would tag my post qa qa-programming qa-javascript. Users can peruse the qa tags they have expertise in and answer other user's questions. The best part is, you can get paid to be helpful! Users that might not be the best writers might have tremendous technical expertise, and this use case would help them be able to get in on earning Steem Power for their content as well.
I think some of the same rules as Stack Exchange should apply. Don't plagiarize. Search for questions before you post. No homework questions. This is a way for us to help each other succeed, not cheat.
I think qa-programming, qa-steem, and qa-photography would be good communities to start with.
