Well! Google is a search engine. So if I search for my name, why should the google plus profile show up first, above the facebook or linkedin profile which probably has a way higher relevance score. Just because you decide to add a widget to detect a name and show the google plus profile as the first result, that to me is hacking the search ranking. From the blog-post, say if you search for music, it might bring up the gplus profile of a famous musician(not even in your circle or friends). Why should it bring the gplus page rather than the myspace page for that musician(which might have a way higher relevance)? That page is public, why don't you show that as the representative page for that piece of information rather than the self-promoted gplus page. It's ok to promote one's own product, all it means is that google search ranking now has a big if-then-else. If google-product, show at top, else push down :p
