Betaniks are hipster programmers always thinking of new programs to release in early beta. They're usually skinny and lanky with the appropriate hipster potbelly. They subsists on vegan food and PBRs. They're very smart, but still socially adept. Betaniks have a wide social network and go to lots of music shows in addition to writing tons of code. Betaniks speaks a lot at user groups, and know what they're talking about.
Betaniks are clever, persuasive, and innovative in their designs. They put together amazing PowerPoints, give compelling talks, use just the right sprinkling of buzzwords like "architectural cohesion" and "cyclomatic complexity."
That betanik can not only remember the internals in System.Web.UI.WebControls.Namespace, but he can organize a trip to Burning Man for three friends.
