"If by renaissance he means adding features and stuff in an effort to attract someone to Google+, then I'd agree it's undergoing a renaissance," Olds said. "I don't see Google+ as completely dead, but it is pretty damned sick. Right now, I think the majority of active users are those who are forced to log into it in order to use their YouTube accounts or other Google services."
The company hadn't come out with new features or redesigns to excite the Google+ user base or attract new users until recently. On May 4, the company announced Collections, a feature designed to help users group their posts by topic.
"Our happiest Google+ users are those who connect with others around shared interests and passions," the company said in a Google+ post. "So we set out to give people a place to express the things they love... Every collection is a focused set of posts on a particular topic, providing an easy way for you to organize all the things you're into."
Users are looking for more than that new feature to put some shine back on Google's social network.
"Well, we just haven't seen Google come out with much in the way of advancements on Google+," said Blau. "They certainly haven't been doing any marketing or real improvements. We certainly we haven't seen much in the way of viral growth. It appears to me that Google+ has been left to the side."
Jeff Kagan, an independent industry analyst, called Google+ a "dud" but he believes Google can turn it around. Maybe the changes that Horowitz mentioned will make a difference in the network's growth, he said.
"I think Google+ has been a pretty big disappointment to date," Kagan said. "However, I don't see Google walking away. I do see them making changes and hopefully improvements. So far, Google+ is pretty much a dud but that's not to say it will always be that way."
