I’ve been playing/using MacJournal’s trial for about 12 hours now. It seems to do everything I want including updates, tags, separate journals for Blogs, private diaries, and even imports. The imports are difficult and take a lot of work but they do happen. The imports do lose some information like tags but the data that is important is the posts.
I’ll try it for a few more days and if I continue to like it then I may transition to it from Ecto which is a big deal for me since I’ve been using Ecto for quite a while.
