Fatal mistake: After Twitter shut Posterous in 2013, Sachin Agarwal relaunched as "Posterous Spaces" — a paid social posting service. Raised $500K. Shut after 3 months when it couldn't acquire a paying user base. The original Posterous had been free; users wouldn't pay for the same functionality. Shortest funded relaunch in this database.
