Use the correct tool for the job
This forum format is the best way to communicate between builders. I have found answers here many times during my build that saved me a call to the factory. I try to give back if I have a useful idea.
Facebook would be a nightmare for searching archives to find an answer. BTW - I call facebook "chick book" because it has turned into a tool for the females to socialize, IMHO. I've seen enough photos of dinner, flowers, shoes, and the like to walk away from my account long ago. Twitter is another look at me social media platform that is worthless to me as well.
I am a member of several forums. I get home from work and check "new messages" of each one very quickly so I can stay up on half a dozen topics. I am in the camp that it will dilute the overall content on both sites. Who here is gonna post stuff twice? Not me.
Man, I am getting old and grumpy
