The biggest challenge most companies have is keeping the blog current. What I always suggest is you must look at it as a prospecting/networking tool that needs to be included in your marketing mix. It is just one more tool in your marketing toolbox.
Charlene's blog has been up and running since September. She's already demonstrating one of the key success metrics of a blog: content that's worth reading and, hence, going back to the blog again.
Definitely a blog worth paying attention to.
