I like the forum model. It allows for a more measured and complete response and easily followed threads that can be traced back for future reference.
Im not a fan of social media, which seems to be more about instant responses and promotion, and which feels restless and rushed..but I expect I'll be left behind by this.
I dont contribute much here,mostly as my active engagement was until recently elsewhere [see below] but at least in the boards I usually go to, good behaviour seems the norm.
I am currently mourning the apparent demise of The Guild, where there was a huge melding of knowledge and expertise, especially on WW2, all willingly shared, and promoted by several figure companies, that I would not have heard about otherwise. I couldn't perceive of that sort of resource being available via Facebook.
I dont care about getting "likes"..if I post photos of my toys I don't need to tot up points!
