Nobody said it's required reading before posting in general.
It's just that there's a thread on the top of the page and the starting post of that thread answers your question, it seems a bit weird to miss that, that's all.
In other words, gradually getting into a forum gives you enough time to acquaint yourself with how things work out and the currently available level of knowledge. If you just register and hit the post button right away you're bound to miss a lot of stuff and then some people will come along to point that out.
Trust me, i've been answering the same "how to" questions ever since the game was released, i compiled some sort of FAQ to have them all in one place for ease of reference which is now a sticky and yet, there's still a few people who manage to completely miss it and ask one of these questions again
It's unavoidable to an extent of course, but it's good to be a bit proactive about things as well and check the most visible part of the forum for anything that might answer my questions before i submit a new thread dealing with the same issue
That's got nothing to do with 1c, it's how forums and communities work in general: people expect any poster to be at least somewhat informed about the matter they are going to debate or criticize. That's not unreasonable to expect, in fact it helps with the flow of conversation and keeps all relevant discussion in one place and easily accessible.
