i think a cool feature for this website would be the ability to set a global stylesheet for all your posts. like if you want all your posts to be in a certain font for example (and i do) you could just put a rule in there. no idea how feasible this would be to implement though.
otoh while it is tedious having to choose the style every time means that all my posts end up looking slightly different which i do enjoy. so i guess its impossible to say whether its bad or not
