Google+ Communities feature was launched earlier this year. We are already seeing tons of communities being created by users on the network.

Finding something of your interest is still complicated. Same topic have multiple communities as discovery is an issue.

Google seems to be working on this problem. Communities are being highlighted in search results. Google is also showcasing Suggested Communities in stream.

It is not clear what parameters they are using for these suggestions. We hope they are personalized based on the kind of content user reads and write!
