To icon or not to icon?

One thing I’m thinking of including on the blog is category icons. I love how these look on other blogs, and it can be a great visual cue as to what a post is about, and where it fits in the larger sense of the blog.

The problem here is that I have approximately 50 gajillion categories! I suppose I could try to combine them a little better: like maybe travel and nature could be together, or relaxation and hospitality.

Here’s a few sketches for idea. Maybe you’ll see them on blog!
