The fine folks over at Curbed reported yesterday that Twitter co-founder Evan Williams (heretofore known as @ev) sold his SOMA penthouse (going for a scant $1,498,000) on Fourth Street. You know, that large megaplex across the street from K&L Wine Merchants? That one. Anyway, Williams bought a fancy new Victorian in Noe Valley. Charming! This comes on the heels of his partner, @biz, selling his own pad for fancier grounds. What's this mean? It means Twitter is doing well. Very well. (Can you give us some money, Evan? Oh, just kidding. Sort of.)
