Having recently become a convert to Grid Layouts, I find myself looking at more and more sites' code and seeing that grids are still grossly under-represented.
While I accept that grids might not always be the only right solution for every web design situation, I think that they are a tool that should be seeing higher rates of adoption than they currently enjoy.
I think if I'd known more about the design approach earlier, I would have saved a considerable amount of time and effort. But Grids don't seem to have the sort of exposure that, say, CSS standards do. Why should that be? Is it even a problem that some people might be missing out on a design approach that could potentially be a better solution to a problem they're working on?
