What do you like best?
Seems feature-rich, for what it is. I tried it and abandoned it.
What do you dislike?
It's not a community site. Perhaps its just me, but for me a membership site implies it is a community site. This isn't that.
Recommendations to others considering the product:
You should know that it is basically a push product, pushing out content to users. It is not a community-oriented site.
What problems are you solving with the product? What benefits have you realized?
I was looking for a community/membership site, so therefore I didn't receive any benefits.
