Shel Holtz has an interesting post on his blog that details a recent dialogue on GM’s Fastlane blog. In it, CEO Bob Lutz explains why he’s been relatively quiet in recent days (or weeks?) and refutes various claims about GM’s purported lack of commitment to the blog. Lutz should get kudos for addressing the criticisms head-on and being candid and real – two critical requirements to be credible as a blogger. This debate reminds me that the best advice I ever heard on etiquette for blogging is that you should treat it as a friendly dinner conversation. That means being direct and honest, but never rude or defensive. It also means being responsive to the discussion and answering questions directed at you – to avoid those would be totally ridiculous and disingenuous in a dinner setting, and they are equally so online.
