Twitter TWTR can be a gnarly platform for entrepreneurs to create a relevant presence, let alone master. Unlike Facebook FB and Instagram, Twitter is a platform that shuns self-promotion while generously rewarding snark, sarcasm and wit.

That’s why so many professionals struggle to establish a relevant presence on the platform. Their cautious voices come off as forced and out of touch with Twitter’s overall tone and pace. On Twitter, edgy works. Shamelessly seeking attention, on the other hand, does not. By and large, Twitter users are sophisticated enough to distinguish between the two.

Twitter rewards snark, sarcasm and wit, and these eight entrepreneurs are not afraid to tweet their minds. They represent a refreshing break from the canned, corporate fluff too many businesspeople resort to online. Follow them right now to spice up your feed.
