Well, every blogger starts somewhere.

I started from personal to web design and development.

You're only one quarter in your journey to find what you really like writing about. As far as I can understand, you like sharing your views of the articles and opinions. From my point of view, you're an opinionated blogger.

Bloggers in this category normally like to:
1. Write political blogs.
2. Write reviews.
3. Write social topics.

Well, you get the idea.

Anyway, good luck in discovering your passionate subject.
