I did attach #beinglatino and #latism to a couple of my tweets, and gained some (3?) followers. I also had one true conversation--someone @me with a comment and I clarified.
ClickZ and Rodriguez both have an air of #corporatemarketingbrandingstrategy, which is not my thing, although it could be if you offered me enough money. Fun is fun, however, and I especially like these three observations by Rodriguez: 1. It's not just about tagging; it's about belonging. 2. It's not about "Twitter storms"; it's about persistent conversation. 3. It's not just about conversation; it's about organization, too.
