HTML is really not all that ubiquitous. The breadth of the technological world is wide... In any case, from my point of view the question is not "could I put together a virtual server with some kind of blogging software on it?" (I'm sure I could) but "is that the most interesting/important/worthwhile thing for me to do with my limited time?" and "do I want to give myself the ongoing maintenance chore of ensuring that the server and software stack is up to date with security updates?". Those two things are why I host my rather-intermittently-updated technical blog on wordpress.com.
