Marc Andreessen has a running series on his blog about start-ups that is – to my mind – a must read.  If you don’t know him, Marc’s the ridiculously successful, interesting, and well-written founder or firms like, oh, Netscape, Ning, OpsWare (which HP just bought for a measly 1.6 billion – yes, that’s with a “b”).   I just read his post on Hiring, Promoting, and yes, Firing Executives.  Good stuff, and definitely worth reading.
