unfortunately making it harder to participate even with a simple quiz may be a turn off for some as we are use to the rapid fire pace of normal social media. It's hard to go backwards when our attention spans are shorter and shorter - or at least that's my view.
Its an interesting point tho!
Good points ;)
My attention span is only short when what is in front of me is not worth reading!
If it is worth reading, I will read it - my attention span is flexible. ;-)
