Rands in Repose, Erik Sink, and Joel (he gets only one mention) should all get a similar amount of play as pg, I'd say. Rands is a fantastic writer, Erik's just as start-up focused as Paul Graham, and a lot more practical and Joel is (or at least, was) the sharpest business / software writer around (and he hosts the business of software wiki - http://discuss.joelonsoftware.com/?W1 ).
