A little bit dated, but it seems like it has been receiving updates. There is a whole section at the bottom now about how to answer questions (ie. don't be an asshole). I really want to emphasize that idea. Lots of FOSS communities now have codes of conduct which I find useful in mitigating this behavior, too.

As for the tone, it definitely has an ivory tower, individualism, pull yourself up by your own bootstraps, slanted view but I don't think it unduly burdens a newbie to learn how to teach themselves by ensuring they've exhausted all the typical avenues of stored knowledge before bothering someone with a well-crafted question. It is a self-sufficiency that has very positive returns in the future.

Without more context, it is difficult to say how justified OP is in their read of the situation. Maybe the forum posters weren't really out of line because the general topic was #random and OP asked in the wrong place?
