I'm a sole founder and I'd love to have a smart, hardworking cofounder. I'm a nights and weekends coder and will likely remain so until it makes sense to go full time.
I'm currently developing (with Rails) a timeline app called Preceden, which will compete with more established timeline sites like Dipity and Lifeblob. I'm in the Philly area, but I'm shooting for the Bay Area in a few years. If you're interested in talking, you can find details in my profile.
