Google+ is still in field trial mode (not even beta yet), with only a limited number of users testing the product. And that's a good thing, because it's far from perfect.
Vic Gundotra, a senior Google executive, admitted on his Google+ page that there was lots of criticism for Google+.
For example, he apologized for the spam of notifications that flooded Google+ users on Saturday afternoon. Gundortra explained that it was caused by the lack of disk space due to overwhelming demand.
Other complaints about Google+ include the inability to completely block a user, bugs with the stream updates, and trouble with the instant upload function. A whole page of Google+ problems/complaints can be found here.
One user on Gundotra's Google+ page said he had trouble figuring out the service when he first started. Others posted many questions on how to perform basic functions. Google+, it seems, may not be the most intuitive product, even for a (presumably) tech-savvy field trial crowd.
From its past failures (e.g. Google Buzz), Google knows that Google+ only has a limited window to gain mass adoption once it's publicly available. Having problems, especially when it comes to privacy, will stir a storm of backlash that could kill the product before it even gains a foothold in the social sharing world.
Google's decision to keep Google+ at field trial status, therefore, isn't just a marketing ploy to generate a buzz.
So far, Google+ users seem to like the service and appreciate executive like Gundotra taking their feedback. Many of them also understand that field trial products are expected to come with bugs.
I expect some bumps. So far it's great,
Thanks for reaching out,
and That's what happens during a field trial I'm glad to be a part of it were some of the supportive comments posted on Gundotra's page.
