In some ways they're even easier to build than they were back then if you use the right tools. Some static website generators these days are ridiculously simple to get started with and can get you rolling pretty darn fast with a quite professional looking and easy to self-host web site (or VPS host, or other site hosting method). The hard part of it all is writing content folks will want to read. Best if folks do what they did back then and write content about things you're passionate about. If it excites you to write about it, that excitement will often be "contagious" to others of similar mindset and interests.
