1. Got comments and pingback with Antispam There are plenty of free/paid, SaaS, self-hosted comment systems to choose from. 2. Install a nice (Elastic) Search plugin with a decent search engine (name your preferred option). Same as above, for most blogs something like http://elasticlunr.com/ http://elasticlunr.com/ can get the job done really well. 3. HotSwap on the fly themes Most static site generators support this. 4. Improve performance via cache plugins (there are a lot of them). The point of static sites is you don't really need to cache data. It's already generated ahead of time. You're just serving the content.
