I just started on my second bow, and you guys are right - it is the vast wealth of info available. Almost any question I have had has been asked before (several times, usually) and thoroughly answered. And that's just the info from this forum. There are at least a couple more out there that are also fantastic (you know which ones I'm talking about). The buildalongs here and elsewhere, like Sam Harper's Poor Folk Bows, offer huge insight and help remove the apprehension of starting up on this awesome hobby way of life.
I think the best thing a beginner can do, other than buying the Bowyer's Bibles, is to open up the "Bows" subforum here at PA and just start plowing through every thread that looks interesting to you. I'm going to go through all ~1000 pages. I don't read every thread, just the ones that are interesting to me now. Once my skill level increases, I will no doubt go through them all again. I bookmark stuff, take notes annotated with hyperlinks and who said what, and I save interesting images. Basically, I am flooded with information. It's like sticking my head under a waterfall of knowledge.
