Wondering the the main benefit to building in public is. Is it getting customers directly from Twitter? Is it getting write-ups and building links for SEO? Does it only work with certain types of businesses? Wondering if it would be a turn off for B2B startups since it would show how small a business is (one man show) and hurt trust.
