I'm not a great (or, really, that good of a) programmer, but I enjoy reading other people's challenges, and thought I'd try my hand at submitting a few challenges myself. However, I don't see myself ever answering (m)any questions (Python isn't that exciting a language to golf). An obvious solution is to learn one of the more entertaining esolangs, but as a senior in high school, that's not something I have a lot of time for. Is it still ok for me to post questions without answering any?
Of course you can!
We welcome any and all participation. How you choose to participate is up to you.
I went over a year without posting any challenges at all; all of my participation was answers. Calvin's Hobbies, one of our most successful challenge authors, almost exclusively posts challenges. At least in my mind, the point of this community is to have fun. Do whatever you have the most fun doing!
A great way to grow your programming skills is to participate in challenges but there's nothing that says you have to.
As a challenge author, the greatest tool available to you is the Sandbox for Proposed Challenges. There you can get meaningful feedback about your challenges before they go live.
