If the API requests come from your server when users view your page, then, yes, your users will be collectively limited to 150 unauthenticated GET requests per hour, unless your site is white-listed.
If your site was white-listed, it would get 20,000 unauthenticated GET requests per hour. You also authenticate the requests using multiple accounts and get 150 (or 20,000, if white-listed) API GET requests per hour for each account used for authentication. If the API requests come from your users' computers, then each will get 150 API GET requests per hour. Hope this helps.

Scenario: I create a jQuery plugin that pulls in "my" status updates (not authenticated using REST). Each person viewing my page (from different ip addresses) hits the API once every hour. Question: Does this mean that only 150 people can simultaniously view that page without hitting the rate limit? Will it be restricted by "my" account rather than by ip? Thanks, Nathan
