Looks like you can't post in existing blogs, nor can you make new ones.

Curious if this is permanent.

Yes. Blogs are gone.

That’s unfortunate. I am glad they left them readable, however. Losing the info on there would have been kind of devastating for me.

I would create a copy of your blogs if you wish to keep them. They may be completely removed at a later date, but as of now they are just read only.
