Because to impose on the flake takes talent, and they have continuous work.

Because to make saytik on Bitrake+Bootstrap(top Studio I've ever seen this bunch yuzayut) don't need a flake :) would Just give money and everything. In larger companies,to understand how,using more modern technology and trends.
Lebedev and Gorbunova also flake almost no bootstrap no. They a serious company? Can you name at least one big Studio that uses the Flex on full? - alba_Feil commented on June 8th 19 at 16:55
use those who need it and who can use them. And Wang these studios support older browsers,why not use them. PS. Tables typeset until the end of the 00-o - catherine commented on June 8th 19 at 16:58
