Title says it all, and I don't have privileges to post on the meta forum. If there's a better place to post this, it'd be really helpful to hear about.
I am extremely confused by this question, but here goes.
Is this a good place for beginners
Yes, definitely. I would say most of our questions are asked by relatively junior academics (assuming that this is what you mean with "beginners" - if you mean beginner in another sense, you should clarify).
to seek information as they learn
Isn't that what most questions are about? Of course, as per Stack Exchange standard rules, you will need to do some basic research on the topic yourself first, the question needs to be generalizable to others, it needs to be in scope topic-wise, and it cannot be a duplicate of an existing question.
or is that type of discussion completely (or mostly) discouraged?
All "discussions" are discouraged here. This isn't a forum. It is not supposed to be a back-and-forth between the OP and the community.
