There's some great advice being posted on Band of Bloggers, a blog set up for Together for the Gospel conference which has a pre-conference 'Band of Bloggers'.
"If you find me short in things, impute that to my love of brevity. If you find me besides the truth in anything, impute that to my infirmity. But if you find anything here that serves to your furtherance and joy of the faith, impute that to the mercy of God bestowed on you and me."
