Any idea where to find a good designer co-founder?
I have finished code of my startup idea few months ago and currently I am still stuck cause my crappy web design skills.
They're everywhere. Pay attention to the products/projects you admire. Look for Dribbbler's that also discuss goals instead of just aesthetics, and also try and find the design posts/comments that are made on HN. They exist but I feel the good ones are an elusive bunch that are often considered/confused with engineers (and maybe that's because good thinking is just good thinking and isn't confined to one profession, but I digress...)
