That's personal blogging, of course, but the format has moved beyond that into a much bigger realm with professionals writing what could be called short essays. Very often, like what I do, it's used for long works and storytelling. In this sense they're no longer "blogs", they're like newspapers or magazines that simply use blogging software because its cheap and convenient.

Personal blogging can lead to problems, though, such as viewing your life as a soap opera with episodes. You stop enjoying moments for what they are and start thinking "hey, I can blog this," which removes you from intimate participation, almost the way smart phones and "Google Glass" threaten to do. Not everybody has the intuition for Gonzo journalism, they just subconsciously become reporters at the scene or actors in a play they've ceased to take seriously.

Non-writer professionals, that is, professionals who don't write for a living such as doctors, programmers, engineers, etc., have adopted blogging software to spread their knowledge, which is both good and bad. Good because it gets their knowledge out into the world, but bad because the blog format is one of the worst ways to do it; blogs aren't meant for organizing reference or working knowledge, their primary discovery mechanisms are scrolls, calendars and "tag clouds", but reference material really needs hierarchies and chapters. A wiki is better for reference material because it encourages the creation of nested TOCs. A blog's list of dates tells you nothing about how to find a topic, so good advice gets lost, and search engines are insufficient if you don't know what words you could use in a query to get what you're looking for.

"Aw... darn... what's the word for that thingy that goes in the whatsit and makes it do that thing," you think, confronted with a search box, while a TOC can at least help you narrow down until you can flip through entries and spot the vocabulary you were groping for.

I've used both the "weekly column", wiki and blog formats, and I've used Twitter and social networks like G+. Here's a site where I use the wiki format to organize both reference material and editorial content:

And this one is where I use the blog format for stories and editorials:

Although with the latter I'm using a platform that allows for either: each "blog" is a page-like unit, so there's actually two separate blogs ("Nonsense" and "Stories"). I'm still experimenting with it, and am thinking about creating hierarchies with folders and TOCs and putting large pieces on dedicated pages. The automatic sequencing of entries that comes with the blog module makes it easier to string them together, though.

When something is personal I use G+, which is cozier because I can make it public or restrict it to friends and family. Both G+ and Facebook have largely taken the "personal blogging" market away from blogging software for this reason. I have felt less compulsion to "feed" my G+ post as I might for a host and domain name and theme and web design that I've paid fees for and want to get value from, so it helps me let go of the urge to be the journalist of my own life and just live it, like I should.

It makes me think that adding more personalization, "themes" and templates to G+ or Facebook would be a bad idea, because it makes you want to brand yourself as if you were a product. "Personal brand" is not a good idea for everyone outside of actors, consultants and novelists.

And nor do I think people should keep everyone "updated" about their personal life, except the things which might really matter, such as a major illness, deaths in the family, moving to a new home, etc.

Finally, I think blogs and even social media are poor places to seek advice. If you really want to reach out and get someone's opinion, it's far superior to go to a Q&A site like one of the Stack Exchange sites. If it's deeply personal you can post anonymously, and if you only want advice from friends and relatives then you might post to Facebook/G+ with a limited audience. Doing it on a blog is a poor option, since the people you want advice from may never even read it.
