OSS needs more UI/UX people, and I think Tantacrul is fantastic for this. His twitter ( https://twitter.com/Tantacrul ) and youtube ( https://www.youtube.com/user/martinthekearykid ) are full of interesting tidbits, an you can tell he's passionate about things. Even if you don't do music/notation his video on Sibelius, https://www.youtube.com/watch?v=dKx1wnXClcI , is ridiculously funny, but also on point.
IMO the problem is that OSS developers hate any change that’s made to a UI because it breaks their workflow. As a result, a lot of OSS has old style interfaces, and it’s hard for UI designers to convince the others to make changes.
And also the attitude of "works for me" really pushes usability people out.
