Theme should have a super-abundance of comments. More comments than code even.
In looking for a new theme I am learning that 99% of theme creators have not a single clue what the word “minimal” means. No clue at all.
The rant continues – you know that technique where they don’t load images until you scroll down? Well here’s the thing – I can see them faster than your code will show them. Stay on your site? No.
There isn’t a single theme that gets Asides right. Not one. So no theme will do until I find someone who I will happily pay to make changes so small that a theme author should be doing it anyway. Of course if theme files had lots of commented code I wouldn’t need to – would I?
