If you are reading tweets from people telling you that they are going to the bathroom then you have some demented friends. I find facebook to be the more juvenile of the two with all of the silly games and garden growing etc. People criticize without knowledge and that is a shame. Twitter is a handy, well used by more than rockstars, social media outlet that has plenty of practical uses. I post one message and whomever is interested sees it. I don't have to type a bunch of emails to get my message to many people. There currently 190 million "twits" using the service.
Thank you for sharing my day.
