Tell YC: Today I went to a Verne Harnish Seminar

I've just come from a Verne Harnish Seminar in Barcelona about Strategic Planning. I haven't heard about him before, but it was really inspirational. After the seminar he made a giveaway of 4 of his books and I happened to get one (which he kindly signed). I think his company, Gazelles, is based on Washington. I asked him after the seminar if he did know Paul Graham and that I followed YC's HN and Silicon Valley Startup Scene, and he told me that he knew Paul Graham, but not in person (he knew who PG is). Have you heard about Verne Harnish? Is he popular in the USA?
