What makes a Good Blog?

I think a good blog should give readers great content regularly. The following are the factors I believe are important for making a good blog:

1. Consistency: The owner of the blog should update the content regularly, at least once a week. 
2. Professional: A good blog should always guarantee that all the content and resources it shares are true and valid
3. Helpful: The most important factor that a good blog should have is helping the reader. The only reason the reader subscript a blog is that they seek useful resources regarding a specific topic. Therefore, a good blog must ensure that the content is helpful.
4. Networking: Sometimes, blogs with the same topic would come together and share links, resources, or even readers between themselves. Thus, I think a good blog should use networking to spread its presence and increase its popularity.
