Why's that Rich? I released my desktop HTML5 game to Kongregate, GameJolt and Newgrounds, and whereas the amount of views for the former two are in the hundreds, at Newgrounds it received close to 70,000 plays and 30 pages of feedback.

For those who do monetize, 70,000 views suggests some earning potential from ads,
