I like Post Kinds but I’ve always been worried about the data if I stop using it in the future. Posts just disapear when you turn it off and it would take a lot of work to put stuff back in again. I’ve been considering adding the appropriate markup manually going forward.
Speaking of Post Kinds, there doesn't seem to be an easy way to export all that data in a way I could use elsewhere? That might make the choice of what to do more difficult.
