C. Reichmuth asked me
"What is the weblog for? Is it somewhat of a journal?"
Yeah, but with hyperlinks. A diary, journal, place to practice
one's writing skills, to point people to other cool sites you've

collaborative development -- of software, book projects, games,
or whatever. Some of them lead into "knowledge management",
where companies can use this form of website on their intranets,
to capture progress and info about particular internal projects.
A couple of weblog histories give some helpful perspective and
links to examples of popular weblogs:
