We just started a blog on our site for a few reasons. The biggest two being spiderable content and natural links that we don't have to actively pursue. Besides histories, and how-to's which are not really appropriate for our site, what other types of information do you post?
We want to start a conversation with our current and potential customers.
One needs only to look at the popularity of reading blogs and reality TV shows to see that people like to peek into other people's lives. Especially when the other person has something in common with them, even if it is just shopping at the same store.
You may also find that your customers have something in common that has nothing to do with what you sell. While I did not maintain a blog, I have maintained several email lists. For one of them, we found that our customers went ga-ga for recipes. Food had nothing to do with what we sold but our customer base was of an age group that liked to swap recipes. So once a month, we sent them a recipe. It kept them interested in the email and they forwarded it to their friends. Think about your customer base and see if there are some "how-tos" that they would like that may or may not have to do with your product.
Read blogs from Big companies like Go Daddy and AdBrite, that should give you some ideas.
