I have been laid up this winter and have been working from home the past several months. Idle hands ARE the devil's work so I decided to take on a machine learning challenge at CodeProject.com and build a recommendation engine like Amazon, Facebook etc. These are interesting pieces of software that in commercial sites can work in conjunction with search engines to lead customers to content, products or items they might never would have looked at otherwise. In fact, this is something that might be useful on LMR - maybe have a recommendations window for when a user logs in? This way, older content that is on the site gets recycled and reviewed instead of disappearing into bit heaven.
I hope someone finds this interesting and useful.
