On stackexchange nobody has a problem with someone asking a lot of question provided they are good, rule-abiding and thought-out.
You can also answer questions of other people. It might even be better than textbook problem because someone well tell you when you are wrong via comments.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
