Sorting Based On Topic And Category

Hi!

Thank you for the list! It's pretty helpful and useful.

I would just like to add a consideration over sorting the list according to categories, domains, and backgrounds. Some blogs are more in-depth than others, some are companies, some are individuals. Finding the right blogs for themselves might be currently a challenge for people wanting to learn from this list. Or maybe I'm thinking about this the wrong way.

Thank you!
