On my About page, I write that I will cover new media, business philosophy, and the good life (including tea), on my blog. My mission is to spread better ideas about these categories.

I have to come up with a workflow for finding featured images for the post, and see how they show up in the blog post, and on the homepage.

What are you thoughts on tags and categories. How many tags should add to a blog post, and how many categories do you need to have for your blog?
