I think the latest trend might be e-courses. I've been taking online writing classes for a few years, but these courses are created from the authors of blogs I've been reading for awhile. The courses tend to be self-paced via email or include a community forum.
These are just a few I've come across:
Sandy's four week, online, journaling workshop will help you take the first steps on your creative journey to self discovery.
Holly Becker of decor8 This creative blogging e-course will help you to get in touch with why you're blogging in the first place by providing lots of helpful tips, feedback, inspiration and ideas that will guide you on your blogging journey.
Susannah Conway - The Unravelling e-courses are designed to help you heal the way you see your self and your world, using photography and journaling to access hidden thoughts and dreams, encouraging personal realisations and ultimately acceptance
Today I learned of one more hot off the press, Andrea Scher and Jen Lemen just started the Mondo Beyondo - an online course about dreaming big.
p.s Video blogs/V-logs are popping up more now too.
