This is true for every platform, not just iHub. It's just easier for startups because they don't have a legacy to contend with. Does legacy have to be trashed so one can act like a startup? No malice intended.
And on the loosening of civil treatment. How can one say that a anonymous member calling another anonymous member a moron and idiot is the same as "I call my friends that all the time".' Is it now okay to call a complete stranger a jackass just because they do it on twit in a throw away environment?
Please keep in mind that Ihub is an archive, not a 30 second mindless bloviate site.
