Blue Sky On Mars is Kevin Dangoor’s site devoted to software product creation topics.
To avoid having to deal with comment spam and to generally just maintain my own voice for the site, I have adopted an old-school commenting format: “letters to the editor”. If you have a comment, send it to firstname.lastname@example.org.
I created Blue Sky On Mars in the middle of 2001 as my personal blog, but it always had a software product focus. My personal blog is now at kevindangoor.com and has taken over as my place to post non-software topics, so you can safely subscribe to BSOM and not worry about seeing random political rants or parenting posts.
