A blog can become a showcase for a person's unique knowledge and skills. With small regular posts one can build a portfolio demonstrating more about their personality and quality of work while building their reputation at the same time.

A blog can also be an outstanding networking tool. This is just the kind of thing the blogosphere was meant for…sharing information, having a discussion, building relationships. Here is an example of a career blog to check out – Publishing Careers by Lori Cates Hand. This blog was built on the ultra easy and free Blogger.com platform.

I love the way she built the blog with the central theme of an informational interview for those interested in the industry. This instantly sets her up as an expert. It also leads to numerous ideas for topics to write about as she discusses her own career journey and daily activities. She also interviews others in the industry which greatly furthers her professional networking activities and exposure. Brilliant!

Here is a discussion forum thread for comparing notes on blogging for career advancement.
