Technology legal news website Groklaw is shutting down due to concerns over the continued availability of secure email in the wake of revelations about U.S. government surveillance. "The owner of Lavabit tells us that he's stopped using email and if we knew what he knew, we'd stop too," site founder Pamela Jones said in a farewell post Tuesday. "There is no way to do Groklaw without email. Therein lies the conundrum."
