Well, I’ve used MacJournal for about 100 posts and it’s a nice application. It has the benefit of allowing you to have a “Blog” and a private journal.
In my view, the weaknesses include the lack of synching a designated number of posts from a blog site which could include download all posts. I like my blogging software to have a complete record of what I posted.
Another weakness is the lack of simple use of HTML tags. Photo’s, audio, video use it’s own mechanism which requires these to be uploaded to your blog but if you just want to link to something, you can’t do it – at least I couldn’t find it.
A strength of MacJournal in addition to the private journals, is the ability to freeform tag. I like this though it could be improved by showing a list of the tags set up in the blog itself.
Ecto has once again become my default blogging software. It has the ability to do or at least work around the weaknesses of MacJournal.
