I won't name the "Uber for Lawyers" service we recently used for a minor task, but it was just as bad as you might think it would be. I would not recommend anything like that to anyone, especially for trivial services.
When hiring another firm I did a lot of prelim research on Avvo.com - they give you a good amount of detail and user reviews without having to create an account. It's easy to find the attorneys who are listed on there without having to use Avvo's system.
I still think the best way to find an attorney in a specific field is to ask other attorneys in any other field.
Having heard horror stories of Uber drivers asking the equivalent of, "Which bridge is the Golden Gate Bridge?" I cannot imagine the clusterfuck that would result from an Uber for lawyers.
