I don't need to support comments/feedback and I'd rather not have to deploy a database and large framework; WordPress in particular has had a bad time recently with serious security vulnerabilities e.g. http://www.welivesecurity.com/2017/02/08/100000-wordpress-webpages-defaced-recently-patched-vulnerability-exploited/ .

I use VFP for my site, via (Martina's and others') FTP API. Generate page, check for its date on disk, overwrite and FTP if newer. Click on "independent" above.
