Generally, it happens like this: A well-known (or under-the-radar) celebrity gets an e-mail from his publicist telling him how he should make a blog to boost his sagging reputation. Said celeb decides to try it for a while, but is never really into it, and eventually it fades into the ether. Sometimes, of course, the celeb is absolutely into it, and these tend to drift into other types of blogs. Other times, the publicist insists on Astro Turfing the blog by posting as the celeb, turning it into a Flog. Some celeb blogs achieve cult status among the geekery (the most famous of course being WWDN).
- As noted above, wilwheaton.net. According to Wil's book Just A Geek, he started this for the reasons listed above, to keep the public appraised and try to build up hype for his career, but in time he found writing the blog to be a rewarding exercise in itself, to the point that it has eclipsed his acting career.
- Kevin Smith's blog, Silent Bob Speaks.
- Science fiction author David Brin has a web page and a blog, both with lots of content. Warning: both contain political topics in addition to science fiction stuff.
- Shirley Manson from Garbage is recognized as being one of the first celebrities ever to keep her own independent blog.
- Major league pitcher Curt Schilling also has a blog. As if Schiling didn't already let us know what he thinks. Often. In great detail. Whether we want to know or not.
- Neil Gaiman started one as a way of promoting American Gods. He still keeps it.
- What you might call a subversion of this: the notorious "Rance" hoax. Basically, in 2004 an anonymous blogger started posting, claiming to be an A (or at least B+)-list movie star. There was all sorts of wild speculation as to his identity, with Owen Wilson, George Clooney and Ben Affleck being common guesses. Eventually he was unmasked as a Hollywood fringe-dweller named Keith Thomson.
- Mindy Kaling (Kelly from The Office) had a blog called Things I've Bought That I Love but it hasn't been updated in about 3 years.
- An in-universe fictional example in The World Ends with You, Eiji Oji has a blog called "F Everything". Turns out "F" doesn't stand for what you think it stands for. It stands for "fabulous", where he suggests media, restaurants, products and the like to his fans.
- Australian pop singer Giulietta's official website started out as a blog, but soon became a bog-standard website.
