The 97% other long tails are good for Adsense but only marginal benefit to business customers.
Not really, for e-commerce especially. A search like "Black Leather Sofa with three recliners" or "green shoes for brisk walking" can be a gold mine. Not everyone can rank for 'green shoes' or 'leather sofa' so long tail was a decent way to get some visitors, but now it's all or none.
