Some topics here about responsive websites from behance / prosite.com are from 2013. Meanwhile nothing really happened. The only thing that happens now (unfortunately) is that google will penalize non responsive websites. I must admit that I'm really disappointed that still no responsive layouts are available in about 2 years. It's really a shame for a company that delivers design related software and websites not to support responsive design for customers in 2015.
Even worse, after stalling off customers with predefined phrases for 2 years, now they are playing dead and not even answering to all these questions.
My favorite lines during this long period. Listing them:
Late 2014, early 2015, in 6 months etc. etc. are also mentioned in some phrases, but as we can all see nothing happened.
It was really ok if behance gave us a clear answer, we wouldn't have waited and create our alternative. I have made my company use prosite too. Probably one of the biggest mistakes I have ever done . We are not the only studio or agency to use prosite either. So clearly this service is also hurting businesses now.
Anyway, personally I am thinking of burning behance action method notebooks and pads we purchased years ago. That's how disappointed I am.
