Topic: Hosting

Hi, I'm a Rails newbie and I just goy my first Rails app up and running, and I'm happy with it.

Now I'm looking for hosting solutions.
On this page:

http://www.railshosting.org/#right_plan_for_you

... they talk about the hits per day.
But how do I have to interpret this?
If I look at the hits I have on my wordpress blog this simply doesn't makes sense.

We have an average of 10000 hits per day.
So if that was a Rails app, we would need a dedicated server?
If I only look at the hits on the php files, there is still an average of more than 2000.

Does anyone have experience with dreamhost?
