Don't worry if you can't answer questions, just providing questions to be answered, when you have them, is often the thing a lot of betas struggle with most.
A lot of betas have an initial rush then a bit of a slump, especially on questions - so people who can post a steady stream of good, relevant questions are much appreciated, and very much needed. It's not all about just rushing to provide the best answers. If there were no questions, there wouldn't be any!
Another point worth mentioning, I think most people here are very aware of the fact that the Raspberry Pi will probably attract beginners in a number of areas, so even very basic questions would still be welcome as I see it.
