"You do not have to do everything; but everything you do, you need to do well."Yesterday I read an article where the author suggested that Google+ is dead. I hope not. As an entity it seems to be a mashup of several ideas, however, as a repository of knowledge it must persist. (unlike Wave).
I'm recalling the 80s when there were many all-in-one applications that were awesome. PFS Write, Calc, Database etc... and then the lead was stolen as brands moved into the dedicated app space. Things would so much simpler if PFS had won the day.
I have the same advice for Google. Keep it lean and simple... and done really well.
