I don't agree with waiting until you know what you'll need.
You have to buy something to even have the possibility to get out there. Of course in time you will find out some pieces of kit you don't like and some you love, but without getting some camping gear it is too much of a hassle to get out there. Of course anyone can take a knife and a loaf of bread, hack away at trees and build a shelter, but that's chaotic.
In my opinion it is entirely justified and favorable to be worried about what other people have. The key is to follow it a bit further - don't just take the first guys kit list and get that. Then again maybe I'm too much of a planner and other people couldn't do it, but that's how I started.
I took several lists - Lofty's books, Ray's books, the post on Paul Kirtley's blog, the kit list of the local outdoor shop, kit lists for bushcraft courses, other camping kit lists and so forth. Then I put ALL the stuff into an Excel table and started deleting rows.
When starting out it is not a bad idea to see what other people have - I've ended up with a pretty simplistic set of kit that way and most of it works great for me. If hundreds of people use Zebra billys, then that's what I'm getting, IF I don't know any better. If I've been out for tens or hundreds of times I'll develop my own idea about what I like, but until then I'd rather get a good candidate, not a bad one.
The internet is a wonderful place for collective knowledge, this forum being one of them. It's better to share a loaf of bread than have a turd just for you. My kit may not be unique, most people use similar stuff. But it works.
