The community managers subreddit is a great place to get advice, network and seek collaborations. With around 1.3k members in the group, there are experts in almost every industry and area of business. Reddit, Inc. itself is a community known for its huge active user base and upfront feedback.

 A great place to soundboard your new ideas or see what others are doing and learn from their experiences.
