Changes

It seems likely that some Reddit bots are automatically blogging postings with the word blog in their URL. So I decided to move my blog from /blog to /article. (Note that article is singular to save letters.) I considered 'paper', which is shorter but not quite right. Likewise study, etc. Also journal(which hits the academic in me), digest (my favorite other than articlealso good), review, bulletin, and pub (which was just too ambiguous).
