Yea things are always a lot faster when you have someone who can tell you exactly what you don't know.
The main difference with Call a Dev is the lack of friction for the devs who need help, and the devs who need work. You just post your question and if someone can help, you'll get a ping with a link to their S/O profile. If you like what you see, you accept the ping and the call starts.
