One of the reasons that businesses take part in blogging is to humanize their companies by creating a personal connection with their customers. Blogging is an informal mode of communication that can help convey the personality of a company and it's employees. A blog that I think does a good job with the personal touch is that of a supplier of items for one of my hobbies, making soap and personal care products, Wholesale Supplies Plus.
The Wholesale Supplies Plus Blog contains information related to their business, and occasionally posts about what is going on in the lives of the people who make up that company. A cute touch that I like is at the upper right, a virtual company fish tank, a web gadget that mimics the natural behavior of fish as they look for food handouts from anyone who comes by.
Some offices, mine for example, contain a real fish tank. I decided to use mine as a subject to learn how to set up a live webcam stream and embed it on a web page. No doubt my fish would like to be more like the virtual fish and get fed by every visitor to this blog!
