Do you find UI inspiration by searching or just have you started following people who pin related items?
Recollecting this makes me realize what a great product is -- it just evolves with you. It couldn't be simpler.
Things you can do to find UI work: you can either follow the boards of people who are relevant to the field, you can also browse what's happening on specific domains ("More from [url]" in the sidebar of the closeup) or you can simply browse the related interests.
Hope this helps!
