I mean, technically, Facebook has had notes since the early days. I know the format and style has changed, but I remember writing 'notes' on my wall that any friend could read in a dialogue box since around 2005/2006 ish?

To that note, very few people I know actually use Facebook notes compared to other blogging platforms.

It's a new redesign: http://www.theverge.com/2015/9/25/9398895/facebook-notes-red...

Facebook has about 800 million features you would never know existed unless you went digging for them.

Facebook notes were a huge part of the platform at first, died with expansion of the Newsfeed and the way statuses work now.

All the notes I have seen lately have this same style.
