Well, a WIP thread with suitable updates is still an option, but some random updates we may have may not fit in any board thread, so less a blog more a bulletin board?
EDIT
Also it can be very useful for IMAGES!
Like when you post an image in another thread, you can utilise the bulletin board thread

as a collection box for your images that you will use in another thread such as say a WIP thread... thus being a two in one hit!
I like hitting two birds with one stone, hypothetically of course ^^
EDIT
If it makes it easier, perhaps a new board can be made containing a thread for each user? [Which they manually create with their usernames as the titles] and then there are no rules in that board for multi posting in your own thread, and anybody can post in them as usual for comments or feedback or support as normal... thus not obscuring the whole thing from anybody either... thus looking like a more active forum as well!
