Okay, sure, if you don't care about the visitors to your site, don't bother with HTTPS.

Personally, I don't want visitors to my site having adverts injected by their ISPs or public wifi networks they're connected to. I don't want to needlessly expose my visitors to having malicious JS being run on their machines. I don't want a MITM to be able to change the text that a visitor receives on my website, and make the reader believe that I said something I didn't say. Especially when the fix for all of this is incredibly simple and introduces only a miniscule overhead.
