You are very unsocial in a thread about social media. But as Shagpile noted in his take on the CASA social experiment;
It's not attention span, it's a way of filtering the countless bull**** and cherry picking what you want to read in detail.
Look up "PAIN_NET" in twi**er land, they have such a thing to save you the endless tedium of reading these posts and you can cherry pick what you want to read without being a crashing bore all the time.
I hope this helps you Bruce.
BTW, what's a "simples"? I hope that's not a throw away insult.
