It would be almost trivial to add a new forum type called Blog that we could use for storing and displaying any obsolete blog entries resulting from the blog upgrade in 2.0 from the GROUPS or COURSE levels.

It would display posts exactly like the news mode does it.

We could put in lots of ifs on all the strings trying to make it look like a real blog but it's probably better to make it still like a forum and use forum terminology to reduce user confusion (its a forum after all).
