1) AdSense was serving some really off-topic ads for a while, and it just looked bad to have ads for San Diego or Hong Kong hotels on the home page of a European travel site.
2) Display ads are an increasingly important part of my revenue mix, and since the home page is the first page that prospective advertisers look at, I'd rather have them notice the display ads rather than the AdSense leaderboard.
3) When the press and publicists for tourist offices and travel vendors come calling, having a home page without an AdSense leaderboard might make a better impression. (I say "might"--it probably isn't that important in most cases, but you never know.)
