John Piper has written a manuscript responding to N.T. Wright's view of justification. Who knows if/when we will see it since he is seeking the thoughts of others on it, but the conversation at Justin Taylor's blog about it is already interesting. Piper wrote this on his summer sabbatical at Cambridge.
Brian Spears writes on the 10 things you'll learn by visiting other churches. Always helpful for those of us who too rarely get to visit other churches.
The Church Planting Resources site is looking good, and is now considered to be 83% sexier (according to Drew Goodmanson). It's a site for "free exchange of information to help build the Kingdom and ultimately spread the gospel."
Comback Churches has some good stuff from Ed Stetzer, including his "Stirring the Waters" articles.
And have I mentioned before the PeopleGroups website? Some good, basic demographic stuff for you.
