flock categories do work. You just have to be careful. Once you hit that Publish button and get the resulting window to select categories – make sure to select the categories and leave it as active selection before you hit Publish again !
You see the window is laid out so that the categories are listed on top and the tags are listed on the bottom. Naturally, one would select the categories and move on to type in the tags – that will take the focus away from the categories you have selected. If you select Publish then, your categories are not honored – atleast on my Mac.
Do the other way – select the tags first and then select the categories before publishing. sweeeet!
