I'm one of the owners of this blog, and genuinely interested in your input on the font size. I don't have great vision, and tend to browse everything at 110-120%, depending on the site. Is your complaint the specific pixel size, or do you think we should have used a different measurement?

As for the developer argument, the problem is that there is no hard line. How big of a project must one complete before they're a developer? You said even a small one, but Hello World is a small "project" and certainly isn't enough.

I completely agree that there is a difference between learning to code and calling yourself a developer. One problem here is that the industry uses developer, coder, and programmer interchangeably, although programmer seems to be currently falling out of favor. (I was once at a party where someone thought that I meant I was a "party programmer" or something.) Obviously they don't mean the same thing, but it's kind of like arguing over the difference between a geek and a nerd at this point.
