You may be proven right, it would certainly seem G+ has huge potential: everyone I know so far, and most of the reviews on the net are very positive. It will integrate into all the others google's products, and with that, google will be the king of social.

But that's not the point I tried to make. Based on the post, my opinion was that Google did not want to renew the deal with twitter (and vice versa) which is strange. They are at war already with everybody else (ms, apple, oracle, facebook) and don't need another enemy.
