LinkedIn was really good idea at the beginnings but as always what is for free you are a product.

After reading few LI posts full of “I am grateful” and “I am honored” or “Thank to my excellent team…” bla bla - you have to think that people in your circle became LI-infected as that jargon is not normal.

Nevertheless. There is an opportunity to start over with a new global professional network. LI concept still makes sense.

That doesn't sound to me like a consequence of their free-as-in-beer business model. It sounds like an accurate reflection of business culture and the way people talk in that sort of milieu.
