Prezi using Steal Satisfaction

Why do I need to log in with other credentials to post when I have a Prezi account?

I do not agree to give "Get Satisfactions" terms of service, but to help the community I must agree. This is very short sighted of Prezi.

Now I've got to waste time an block both Prezi and Get Satisfaction from my Facebook account.

The Prezi attitude toward community sharing is worse than Microsoft.
