I'm pretty sure that one clap is the result of a new person not knowing you could clap more--the Facebook syndrome. I'm not sure 50 means extraordinary. I usually clap 50 if I like a post. I sometimes clap less if I do not, but is rare. If I take the time to read nd think about an article, I think it deserves attention. If I don't get through it or feel it is poor, I just don't clap at all. Sometime my device slows or stops somewhere in the middle and I just give up and leave it there. Who news what really motivates others!
