The reason I'm asking is I still don't understand what you are trying to build and what types of blogs it is for?
A lot of the decisions don't seem to follow any strategy and sometimes conflict.
A lot of the features seem to cater for quite basic personal lifestyle blogs, but nothing else. Nothing close to Wordpress.
A lot of the community site/multi-author blogging features, which is the area I'm most interested in, seem to have vanished overnight without warning. Originally on the new wix blog, it could be set up that anyone can "post" to the blog, now you're saying use Wix forum instead !!
If I don't know what you are building, and you're not consistent, I can't use Wix. In fact I'm very close to never touching Wix again, after my experiences with the Wix Blog team.
I'll recommend others use Wordpress or Squarespace as they are better supported blogging solutions.
