March 05, 2012: Skip the promo
When presenting at conferences, webinars, or any other venue, spend as little time as possible talking about your business (or your association). That's not why people attend.
They come for the information you provide. Your value comes from being the source of that information.
So, keep the intros short (7 seconds, not 7 minutes, would have worked for this one) and provide content people want. Don't hijack the audience by forcing it to listen to promotional copy and don't just share a bunch of teasers.
When people find value in the info you present, then they'll be more likely to hire you or join your organization.
