Well, I think my June challenge was a moderate success.  I made 23 posts on derekhat.com in June (archives here) and 4 posts at ardentdev.com/blog.  They did not trigger the types of conversations with readers I was hoping for, but traffic on this blog was up 40% over the month before.  So I think I will continue to post at a similar level of frequency and see if we can get some conversations going.  My target will be 4 to 5 posts per week.
