If I may add a few things:
1. I think most of the comments here concentrate on price alone. You need to remember that email marketing is a tool. If you have even 2000 subscribers and not making $30 from that list:
a) It's your hobby. No problem. Hobbies sometimes can get expensive.
b) There is something really not right with your list/efforts.
2. All the people outraged at Mailchimp's prices should compare them to the competition and see that most of the companies offer similar pricing.
3. Try explaining successfully to your local restaurant manager how to set up his/her own mail server.
4. After you have successfully explained #3, try explaining all the regulations and SPAM compliance.
5. Finally - Mailchimp is for small and mid-size businesses. Once you go over $1000 in email marketing costs you are in a different ball game.
