Recently LordL and I have been talking about how a lot of people don't really treat facebook as social media, in the sense of something interactive. Many people have posting patterns that don't necessarily reflect their real life personalities (i.e. someone very reserved is bombastic online). In other cases, the posting pattern either reveals or highlights less than desirable personality traits (like a propensity to get into angry political debates). I'm wondering if there are any potential etiquette guidelines for this sort of thing.
The scenario prompting this is a relative of mine who uses facebook so infrequently I forgot he had one. Looking at his history, he usually posts every 2-3 months, to say things like "Merry Christmas from the Jones Family" - never any personal updates. Recently, he and his wife decided to do major renovationsto their home - building on an additional floor. Since that process started, he has posted pictures at every stage of the construction process - a pic of the permit, each stage of building, etc. - probably 3 times a week. His wife also posts most of the same stuff so it shows up twice in my feed.
It struck me that if this was about phone conversations, and normally I heard from him every 2 months just to say "hi" or "Happy <holiday>", but then suddenly he was calling 3x/week to tell me about all the minutia of his renovations, it would be inconsiderate and self involved, if not verging into rude. Same thing if it was in person, and he went from infrequent holiday visits to showing up to my house or suggesting we meet 3x/week to discuss the renovations. I'm wondering if and why this behavior is viewed differently if it's on facebook. I know a lot of people believe you can use facebook for whatever you like, and very few rules apply (i.e. no graphic/obscene posts). But why is this? If it's supposed to be a site to share your life with others, does it matter how you do it?
