I have abandoned all pet projects for this new venture. Essentially I'm building a family portal of sorts. Primarily it's going to be for my family, but it will be available for anyone as an open souce project. I've written an article describing the background and goals that you can review.
My blog will serve as my main update site (watch the CodenameTBD for information). Technically speaking, I might use gotdotnet.com's workspaces to share the code... and maybe even get some help (someone help with graphics)! After the website, I plan on making a windows form-based application that will be dedicated to managing a digital photography suite (digital photography is quickly becoming a passion of mine).
