So I'm a self taught web developer but have only been doing it for a little over a year. Therefore, compared to other people, I'm still pretty new to the field. I had a quick question for those of you out there familiar with wordpress and html5. I was wondering why it was hard for me to find, highend, paid wordpress themes that utilized the more semantic html5 tags such as article and section instead of the typical, div class = "section", setup. Take a look at this paid theme for example, which upon inspection makes use of the header and nav tags but not article, section and aside tags:

I've seen a bunch of others they looked the same. My main question is am I wrong to judge these sites for not using the basic html5 tags mentioned above? I thought these tags were important in giving google and other search engines more semantic code to look through. The reason I ask is I'm considering purchasing a wordpress theme for now so that I can get my site up on the internet quickly while in the meantime develop my own design for the future. I do not want to pay for a theme that is not up to standards, if those standards are relevant today. Any thoughts would be appreciated. Thank you.
