When Dell started blogging in earnest a year or so ago, we figured we'd be hearing some PR fluff, and perhaps some damage control now and then. What we didn't expect was self-damning posts about sneaking into the competion's conferences to try and swipe customers. According to Direct2Dell, Dell gave HP partners a "sneak peek" at a new ad campaign by squirming its way into a HP Americas Partner Conference in Las Vegas last week. Dell ninjas managed to hit up approximately 800 HP customers with the ad before they got shut down be security. Classy, Dell, real classy.
