I'll bite. What makes WordPress too heavy in your regard (I'm a huge fan of WordPress my self, so quite biased), is it the way you use it, or the themes you use?
At it's base, WordPress is quite simple, and it's the themes that define what it looks like and feels like to your users. If you are looking for something very simple then there's the simple twenty twelve theme which is very clean. The theme directory on wordpress.org is also full of themes, there's even a plugin that transforms your WordPress into "Ghost" (The same feel and layout).
But I would love to hear back on my original question as well regarding it being heavy.
