Whether it is posts about engineering projects or new products. Career questions and advice. Trends within the industry. Suggestions on projects. Inside scoop on how certain companies are like to work for, or work with.
You need a critical mass of people to sustain a vibrant community. Reddit was decent for getting new a constant flow of new posts by a rather large number of members.
