Not everyone may side with me on this, but link rot and 404s are ok as long as you control when they happen. The web is a human, organic place, and humans are messy, break things, and change their minds, and it's ok for the web to reflect that.
Foresight has been an active business since 2008, and a few things have gotten moved around along the way. If you've ended up here, visit the homepage or contact me and I'll help.
