Tone varies from person to person, post to post, article to article. There is a time and purpose for every tone.
Today, most online articles are written in a conversational tone, which is a giant leap from the "reporting" or "speech giving" tone of yesterday.
Even a conversational tone can vary. You may chose to "converse" tongue-in-cheek, you may choose to use slang, you may choose to use sarcasm, you may use assertive or powerful words.
Practice a variety of styles and see what works for you.
If you're trying to brand yourself, you will want to stay with one style.
