An attempt to decipher why certain blog posts get a lot of comments and others don't did yield only one useful insight so far; there's lots of off-topic stuff in the comments.
This blog was never meant to be an alternative to a discussion board as are the MilPub or Think Defence blogs (just examples), but an occasional open thread doesn't hurt.
So be it.
(And spare the next few threads with off-topic comments! ;) )
