It’s a main purpose of the forum, and speaking for myself at least, people asking questions is a chance to practice my own research methods (and get a little hit of validation). So as learners, answerers get something out of the questions too. And it’s not like it’s gonna be a burden on anybody when we’re here of our own free will, after all!
When I answer questions I try to remember to mention how I found the answer, if I did a search myself, in case you want to try to get better at searching for your own sake. Like in English, with the right search terms, a little can go a long way. But early on, asking here’s probably easier and quicker anyway!
