i post from work... it's my downtime... keep it up in the background on my desktop. i claim it helps me understand the industry, customer motivations, upcoming models, market perception etc... really, just keeps me from going crazy.
so for me, not much of a change other than the fact that i have to click the forum article prior to the article (i normally do it the other way around).
as for facebook... nope. i don't EVER post anything from the fb links. i've had a lot of things i'd like to say on other sites, but due to the facebook link/login, i don't... probably helps me sound less like a moron and kill braincells having an online argument with trolls.
