‘Writing, blog-style’ or ‘Blogging’, to me, is like journaling – writing in a journal/diary.
It’s more to do with the blogger than the topic itself; it can be about the blogger’s life experiences, trips, career, tutorials, opinions on things – this could be anything from interests, hobbies, politics, religion, family, causes, relationships, etc.
Most importantly, it carries a conversational tone as opposed to a neutral, strictly-informational one.
A blogger, to me, invites you into their life and shares stuff with you – as personal or not as they want to.
Blogging is like having an open diary.
