i can create a post, but any tags i add to it won't appear in the tag list, and i can't figure out what i'm doing wrong. this happens on the dev server and the problem carries over to my built site.
I see the issue. There's no actual problem with the software, but I left a typo in the installation guide... 
You've got to write "tags" in the front matter, not "tag". (Even if there only happens to be one tag). Thanks for bringing this to my attention, and sorry again for the annoyance. I'll update the guide.
