Maybe, but with one caveat. I would want to have the advice from 2 or more people, and only if they couldn't see each other's responses. It's hard to know when programming advice is wrong if you're not familiar with a language or a framework, so there'd be no way to know if the advice was actually useful. If I could get 2 or 3 people's answers to the question and they were all the same that would increase my confidence that they're actually right, and that my $25 was well spent.
As a developer I would also be quite happy to sit with a chat app open answering questions for $5 each if I could choose what to answer and there weren't too many problems actually getting paid.
