If you want your content to be read, that's obviously a different matter, but blogging framed as "notepadding" seems somewhat disingenious?
I dunno, but my impression is that blogging is done with some degree of underlying desire to reach out to people and have your writings read (which is fine).
Blogging (with a domain) is more expensive, more cumbersome, less write-friendly due to HTML and .md syntaxing and formatting and it's also laced with the entertainment-complex (it might be read by someone so it should be good writing). But in my opinion this entertainer-complex makes your writing more edgy and attention-seeking (which again is fine).
That's my ramblings :) -... -.-- .
