I've re-enabled comments on unto.net.
I deleted all of the old comments and added some new anti-spam measures to prevent blog spamming. Those measures aren't sophisticated, but should be enough to at least get the spammers to read this post before they try to find a work-around. So to the potential comment-spammers, I say this:
The comment fields are for people who want to leave me a relevant message regarding the post. They are not for advertisements or links to other sites. Comments must be added by people, and by hand, not by scripts or robots. The comments themselves are accessible only via a rel="nofollow" tag and thus won't be indexed by search engines. And, if the comments are spammed, I will simply add a more difficult Turing test to ensure that real people are filling out the form. So please, move on to another site. It's not worth either of our time. Thanks.
To everyone else -- have fun! I enjoy reading the feedback.
