Someone's tried it before: http://www.nutritionask.com/
With a bunch of widgets, changes in the design. And now you can sort by upvotes too so it's probably much more possible to do a Q&A style site than it was a month ago when you first asked
Re: Custom font from acp ?
It seems when we embed google font from acp it works. But if we use google font in our style file it does not work well.
The weird thing I experienced is when I changed my font setting in phpstorm to "Ubuntu" and then I pushed my changes in git using built in plug-in in phpstorm and later udpated my live file, I found that my font-family was overwritten in body, h1, h2, h3, h4, h5, h6, .h1, .h2, .h3, .h4, .h5, .h6
Any clue?? whats happening here ....
