A previous thread mentioned that Google's executives were not using Google+ very much. Maybe there is a reason for that.

Steve Yegge, a Google employee and former Amazon employee compared the two environments. He wrote about what is wrong with the products, such as Google+, the development process, and executive decisions at each company.

"The Google+ platform is a pathetic afterthought. We had no API at all at launch, and last I checked, we had one measly API call. One of the team members marched in and told me about it when they launched, and I asked: 'So is it the Stalker API?' She got all glum and said 'Yeah.' I mean, I was joking, but no... the only API call we offer is to get someone’s stream. So I guess the joke was on me."

His memo was apparently intended for access only within Google, but was posted publicly. Copies are now available on a number of other sites.
