For me it's the opposite. I almost never hit hourly limit, but I hit weekly limit in about 5 days.
What does your usage look like day to day? Are you using a low level amount all day long? I'm with the others here, I've never hit the weekly limit ever, only the hourly, and I consider myself a heavy user.
Would be more meaningful if everyone said what plan they are on, as there are 3 different ones that users could be discussing.
