Many posts are made without a category. I suggest this is made required, to help people sort through the posts.

Hmm… not going to happen then 
I usually take care of this right away but have been on vacation. I just added categories for the recent batch of posts.
Ok, great. Hope you had a nice vacation 
It is possible to make category mandatory in the /admin settings if that is what you want to do @stevebaer. Up to you. Fully supported.
