It totally did not fail. It is the most useful realtime chat for many topics I am interested in:

    #python for the python language
    #php for the php language
    #javascript for the javascript language
    #django for the django framework
    #laravel for the laravel framework
    #symfony for the symfony framework
    #startups for startup stuff
    #css and #webdev for web development
    #mysql for mysql and mariadb
    #math for math related topics

And many more.

Show me any other chat system where you can go online, ask a question and get answers from professionals in the field instantly. I would immediately use it. But there is none.
