What do you like best?
I don't have to integrate and keep up with lots of add-ons such as a Learning Management System, host / server issues, blog, and many more rich features.
There is a ton of educational and knowledge base support. In truth that alone is probably worth the price of admission if one takes advantage of it, plus you get the platform.
The Copyblogger approach is a wonder soft-sell, not in your face Dan Kennedy style approach. It emphasizes authenticity and the art of being subtle but not hidden.
Customer support has been great when needed. Tickets answers fast and accurately.
What do you dislike?
Making the leap from a free Wordpress site to Rainmaker's monthly payment was an initial barrier. What it really meant was I needed to have my business ready to benefit from Rainmaker.
Rainmaker is a package. For power users, I hear them tell them it doesn't give them the oomph they want.
Recommendations to others considering the product
Rainmaker lives nicely in that space between a pure do-it-yourself approach and a custom solution.
What business problems are you solving with the product? What benefits have you realized?
A gateway site to a variety of offerings: consulting services, information products, books, speaking, On-Purpose Minutes videos.
Rainmaker has met my needs nicely.
