Some really good points there Jeff, and will have to read Grace's post as well. I think before anyone, especially the casual user or blogger even tries them, we will need to educate them more and more on it. Even then, I'm not sure how many will get very excited :).

I remember at a local WordPress meetup when myself and someone else was doing a presentation on what we might expect to see in 3.7, and asked how people were more casual users and bloggers, not designers and devs, to raise their hands, then asked for any of them that understood post formats to keep their hands up, every single one went down. Even an overall poll with everyone showed very few people who would use them.

Myself, well, I never use them at all. What can I say?
