We had a slow week here at xmog.com, and decided to try our hand at building a tool for design/development shops like us to share UI assets. Based loosely on the the GE story in Lean UX by Jeff Gothelf, Styleboard helps teams work from the same set of UI elements, which not only leads to a better looking product, but helps developers bootstrap and test ideas without needing the involvement of designers.
If you guys are interested in checking it out, just fill out the Mailchimp form and I'll send out an invite code as soon as possible. We'd love to get any feedback from designers or developers that might use a service like this (alone or in teams).
Fair warning: Currently Styleboard is in a closed beta, which limits the use to a single person/project. We're working on building out the "team" features of the application to make it much more useful in a company setting... that being said I expect a lot of "why is this any different than codepen.io," etc. We're working on it...
Thanks in advance for anyone that signs up and provides feedback!
