So if any newbie is reading this please understand i say with 100% confidence that bitcointalk.org is the most friendly and welcoming place for you to learn discuss about cryptos and relevant technology.
I'm more an observer than a poster yet, but I can at least agree in part with you. There are many really nice and intelligent people here. On the other hand I also saw some quite harsh reactions to the less well informed.
Overall the forum is a great informational resource with tons of interesting topics around bitcoin.
