I have worked on several web based projects. I recently created NerdlyNews, which uses Bayesian logic to grab interesting news from sites that I really like. I’m using a wordpress front-end for that one, and the JetPack extension so I can have the output of the Bayesian algorithm posted to the site using WordPress API’s. It’s really a nice way to go since I’m not a UI designer.
I also created PageLoadStats. This one is a performance monitoring tool with a pretty straight-forward front-end that graphs the data it gathers. This one is very useful to me. You just need to tell it what URLs to monitor, what the alert limits are, and it will monitor, graph, and send email alerts.
