Ask HN: How do you blog for your startup/site?

I tend to develop with Node.js/express using EJS as the templating language, and have several sites with a blog, but I've never found a great solution for keeping the blog in-house.

I tend to use Blogger or Tumblr or something like that, but it's a pain to keep the look/feel the same.

I've seen various static-site generators such as Jekyll, but I really want to be able to reuse my main site's header.ejs - and I haven't found one that does that.

Any thoughts?
