I use quora for my dotnet related queries.
The experts suggestions help me very well to solve my problems.
Recently when I got an issue in multi threading related issue I got answer from quora experts, my problem solved.
The main advantage here is we can read the already existing problems and we can learn something.
The way they designed UI is very good.We can write the questions and ask the questions easily.
The information provided in quora is very relevant and useful.
I suggest the technical guys can follow quora for solving their problems.
