At least, there shouldn’t be. We’ve passed that era. Any business of scale and worthy of going public, as LinkedIn did today in spectacular style, isn’t a dotcom. It’s a real business, with significant impact in several important markets. In LinkedIn’s case, those markets include publishing, recruitment, and professional services. So what if they are leveraged over a digital platform that has a “.com” address? At this point, that’s pretty much the entire US economy, not to mention a significant percentage of the “rest of the world.”
I’m tired of the easy comparisons to the dotcom bubble. They simply aren’t accurate.
