Famed tech entrepreneur Marc Andreessen will now answer any question you lob at him. But it’ll cost ya. The Netscape cofounder returned to Twitter after a five month hiatus Thursday with an offer to ask him anything (anything!) for $20. The proceeds will benefit Black Girls Code, a nonprofit organization devoted to encouraging young women of color to enter STEM fields. Ask me anything! $20 per answer. All $ goes to @BlackGirlsCode.

One particularly controversial Tweet was directed at someone who compared Facebook’s “Free Basics” program, rejected in India because of net neutrality violations, with colonialism. In response, Andreessen tweeted: “anti-colonialism has been economically catastrophic for the Indian people for decades. Why stop now?” (He later apologized.) In September, Andreessen announced that he was temporarily leaving Twitter. “Taking a Twitter Break!” he wrote, deleting all his previous Tweets. The question free-for-all is hosted on 21.co, which lets users charge people to email them. Andreessen’s venture capital firm is a lead investor of 21.co. His public page says he is “happy to field tech-, business-, and finance-related questions.” So get your pitches ready.
