You could also set up a master geeklist (folk subscribe to follow your session reports) or even still do that blog that links/includes your session reports as blogs give you spare space to communicate with your followers. This way you create multiple paths for users to follow your work.
Oh, that's a nice way to combine the two. I like that.
I'll start with regular session reports and then I'll see if it's worth combining them in one of the ways you suggested. Thanks!
