Like @mariachimacabre said, the battlenet forums have been awful almost as far back as the World of Warcraft beta. I trust nothing that comes from that place. I am 100% sure the stability of the product will be fine when the game comes out.
The sad truth is that even with the awful forum posters and loudmouths of the internet - it will still do well.
Something about the whole, "let's rally against this game on the internet" thing is very off-putting.
