In my opinion, blogging is meant to be casual/informal. It should reflect the personality of the blogger. Formal articles can easily be found on Google, we don't need bloggers to reshare those unless they have their own experience about the topic to share, like you said.

According to my experience over the years, I have learned that the more you are yourself or post stuff that is relatable to your audience, the more it gets traction.

For instance,

Instead of posting the health benefits of strawberries, I would be more interested in it if a user shares a recipe that holds nutrional value and which he/she personally tried at home.

Content like this is relatable and looks practical.
