Lets remember, that there are a lot of new people, and people less technically savvy than you and I that come here.
Perhaps they come here to learn/educate and become more of said tech savvy person.
I was new once, as we all were. Do you know what I did when I was new? I read, and read, and read, and read. And when I thought I had read enough, I read some more. I believe I was a member here for a couple of months before I even made my first post because I understood the nature of this site. It's called XDA-Developers because it was started by developers, for developers. It has evolved a bit since then, but it still may not be the best place for new people to learn the basics of rooting and forum etiquette. There are other sites that serve that purpose. Once a person has gained experience at those other sites, and learned how to navigate through and search a forum for answers, they will probably find the waters much easier to tread at XDA. I too have seen the examples of people repeating questions recently asked and answered in a thread. I even saw one example where a person asked a question when the answer was literally two posts up on the same page. I know not everyone has time to read everything, but reading the OP and last say 5 pages of a thread shouldn't be too much to ask.
A related iteration of this, which I feel is worse is the request for links, especially links to info found in the same subforum (ie: user A asks a question in the S5 Q&A section, user B responds saying the answer can be found in the sticky roll up thread found at the top of the S5 Android Development section, user A responds back, "link please?") Is it really too much effort for user A to navigate over to the development section, or does user A not even know how the forum is structured because they have only ever been spoon fed links? It's like the proverb, "give a man a fish you feed him for a day, teach him to fish and feed him for a lifetime." If new people are coming here to learn/educate themselves, they should probably start by learning how the forums are organized, how to navigate around the forums, and where/how the information is organized and grouped. Constantly handing someone links teaches them none of that. A lot of people here spend a lot of time helping people and answering questions. But if people are not willing to help themselves and put the effort forth to learn things, then that is pretty much on them.
I know this is rather long, sorry about that. I just had a lot on my mind as relates to this topic. This isn't meant to be mean to or discourage new people or anyone from asking questions. People should ask questions, but doesn't the learning/information gathering process involve looking for the answers yourself before seeking help?
Just my long-winded thoughts on this.
