I find out that for a twitter card the ordering of head tags can be important. It would be nice to be able to organize them visually. I think that might be possible in the BSS app, don't you think? See image what I mean ...
Just curious, where did you read that the order matters?
I haven't read it anywhere ;-) To get a twitter card working it sometimes takes a lot of searching to find out where the error is in the code. In many cases it has to do with the robots.txt on the server. But you also always look for the code error with yourself. In the UI of BSS there is a window where you can add the meta tags. It would be nice that the order of the fields you see there is the same as the generated html code.
