What has interactions on Online Communities like Bayt.com taught you about Social Psychology and Marketing ?

I had a realization that engagement on social media needs time and nurture and requires a certain FOCUS.

This is also true of business. Resources avaiable to an entrepreneur are limited and if he spreads himself too thin, he is bound to waste a lot of resources on ineffective results.

I am wondering what others have learnt by actively about the nature of things by understanding psychology of the people in online communities.
