The good folks over at the American Marketing Association say they still have some seats for their "Hot Topic: Search Marketing" in San Francisco on April 20th, 2007, but that spots are filling up fast.
This is a one day super-concentrated event with solid speakers. The topic is what's new and important in paid and natural search.
If you're in the SF area and free on April 20th, this day will be well worth it.
Sign up soon, before they sell out.
