I think you answered your own question. Forums and social networks are different now. Originally, forums were for communication, just like social networks. However, now they've developed more into a discussion - which social networks can't offer.This is meant to be a discussion and I want to hear what you think.
Maybe not on Facebook but their is a lot of talk from webmasters on Google+. You can follow pages like Google Webmaster Page, people like Matt Curtis (head of Webspam on Google Search), Google employees who work on websites such as Pierre Far, Susan Moskwa, John Mueller and outside Google follow Search Engine Land, numerous developers, coders, SEO Specialists, Marketing and Monetizing Specialists etc. Have all these in one circle and you'll have a excellent stream on managing and controlling your website.I think you answered your own question.

I agree
Forums will continue to stay alive - but only for discussions on a niche - such as PS3 games, Webmasters etc (you wouldn't find people talking about webmaster stuff on Facebook now would you?).
More proof of this is blogs are managing just fine, even though twitter can be used to find out news people still use BBC news blog, mashable, torrentfreak etc.
So your saying trolls only exist on forums but nobody ever trolls on Facebook, Twitter or other Social Networks?Reasons why forums are dying spammers trolls and admins either to not do jack shit to stop this or is gets way outta hand to fast and they can not handle all of it.
Let's face it: Social Networks totally SUCK. There is no control whatsoever or room for creating the environment of the community. Also nobody really wants to discuss on a social network like facebook which is practically owned by the CIA. Also: Your Group/Page can be erased or 'taken over' by facebook any time for any reason. Especially facebook has demonstrated very often in the past, that you can never rely on assets you have with them. And they excuse everything they do by saying that they are a free service. facebook, above all, is a highly unprofessional service, where the parameters of cooperation and even the design changes all the time, mostly for the worst. I would never ever entrust my business with amateurs, cause that is what they are, at best.
