I think this post really shows cultural differences in the term 'friendship'. Where I grew up (in Germany) most people I know would not abandon friendship because they read a blog post. a real friendship is something special that you maintain also in difficult times and sometimes people are jealous, but that can change and I think the understanding of friendship as a kind of 'success accellerator' is something that sounds quite stange for me. From my definition friendship is exactly the kind of relationship that comes without such expectations
