How can blogs be helpful in a work setting?

Thing 3:
Grab yourself a blog in 3 easy steps.

How can having a blog help our co-workers or patrons? A perfect example of this is the blog of one of my co-workers -- Criss Library Focus On Online.

Blogs can be used by the Library as a whole for things like informing the community of events, new materials, or anything else the library wishes to publish. It can let patrons and co-workers know about helpful websites, which is how I’ve used my internal blog where I work. Okay, so no really new ideas here, but Library Blogs have been around for a long time now.
