It's too bad many of the toughest problems in companies are more typically on the integration level, which requires domain knowledge and context of the project itself. To solve these problems don't require brains, but time and communication.

I feel this service is targeted toward people who have simple one-off "puzzle" problems ie. write me a quick recommendation algorithm for a data structure of this format.

I'd be interested in seeing some case studies to see what exactly are the types of problems you are solving. "Small programming task" is a bit too vague for me.
