Today I finished an upgrade to MexIT (my blog): from today you can post comments. The Perl CGI program that I wrote and added to this site sends your comment by email to me. If I consider it relevant I might add it. The way it works is still quite primitive, especially on my side, since I have to manually add each comment, but this way I can test if people are really going to use it before I put more time into it.
Another reason why the comments are not added directly to the comments page, other then preventing comment spam, is that my entire site is statically generated on my computer at home. Hence I have to add comments to files on my computer, regenerate the site, and upload each new page. A process that has already been automated for a part, but more work needs to be done on it.
