I'm always interested in learning new ways to make my blog better, and a site that relates to this that I like is Glenn Abel's site, writeforblogs.com.
He gives lots of tips and insights that apply to writing in general, as well as writing blogs in particular.
One of his posts recently included a quote from the wonderful Brenda Euland, whose book, "If You Want to Write: A Book about Art, Independence, and Spirit" I love and re-read once a year or so. She said:
“I learned that you should feel when writing, not like Lord Byron on a mountaintop, but like a child stringing beads in kindergarten --- happy, absorbed and quietly putting one bead on after another.”
By the way, I just looked her up in the Wikipedia, and it reveals that apparently poet Carl Sandberg called her book, "the best book ever written on how to write."
