What would be your top 5 qualities for a Pro Blogger to have?

I posted the following comment to a ProBlogger post that asked "What would be your top 5 qualities for a Pro Blogger to have?":

Be concise and to the point with minimal rambling.

Have a little wit, but not too much.

Be a little opinionated, but not too much.

Teach me something I didn't already know.

Introduce me to somebody I wouldn't have met otherwise.

Now if only I could meet those five qualities.
