Hello,
I've started a blog on github at tmckayus.github.com. This will be mostly dedicated to Cumin, although I might post other technical things there from time to time.
For a specific atom feed that contains only cumin posts, you can use tmckayus.github.com/cumin.xml
If you have ideas for blog posts, feedback, or content you'd like to submit for a post, you can send an email to this list or to me at tmckay.redhat.com.
Thanks!
Trevor
