Work uses for blogging

I decided I would try to use my internal blog to keep track of certain docs I use from time to time to set up Exchange server or manipulate my development environment.  They'd once been e-mails, then later modified and dumped onto a share.  Since I am experimenting with self-publishing / blogging, it was natural to dump them on the site.  Now they're categorized and of no real interest to anyone else but me.  Perfect blog entries.  Ahaha...

Would love to hear how others use blogging for work...  Feel free to drop a comment.
