Funny how that works. In it's 'early' days - FB was the social media spot for interactive conversations - not saying it isn't now, but it's definitely changed - and last time I was on (almost 2 years ago for my personal account!) - it kind of reminded me of two old ladies talking/ yelling at each other at the same time.
People are excellent at ruining things with their need for attention (referring to FB here, not you mixing up post lengths on your blog -which sounds like a good idea!)
