Participation is a HUGE part of the online social world. If no one participated social media would not exist – this is most blatantly obvious when it comes to things like reviews and forums.
Personally I find myself often lurking without contributing (which makes me the same as what is thought to be about 90% of people online – http://www.nngroup.com/articles/participation-inequality/). However, when I am given the option to “Like” something I’ve noticed I contribute consistently through expressing my approval (or disapproval) without words. More infrequently, I can be found as a contributor on topical forums. However, although I may remain a consistent contributor for a few months I often find myself becoming taxed by the constant stimulus and pressure to respond and will disappear like a teenage runaway in the night – cutting ties to everyone and everything on the forum. On certain forums I may reappear again, but this is rare and it may only happen after months of absence.
In my work as an information profession I’ve found that when it’s part of a job or a project I actually really enjoy communicating with others and the intimacy of remaining in close contact. It’s primarily when it comes to my personal use of social media that I become wrapped too tightly in the online social world for my own comfort.
