I think it's a nice concept and don't have any problems with it (in fact, it looks quite nice), but I do wonder what distinguishes these various services.

Here in NYC, there are several "Uber for" maid/massage/anything else you can think of services, and apart from the design of their sites and sometimes the pricing scheme, it's hard to tell what's actually different.

Maybe the same thing could be said about Lyft, Uber, etc., but I do wonder what kind of competitive advantage these services are going for.
