You could sell the site on http://flippa.com
Imagine: You have a growing successful website and you wonder what to do with it, would your answer be: I should sell it on flippa? I think this is a poor advice, especially in an entrepreneur community.
I am not taking sides on whether entrepreneurs should sell their companies. But I think there is a problem when bringing up the subject is frowned upon on. I am unsure whether this is a problem with Hacker News' moderation system or it really is a taboo.
