It’s super hard to get involved as a UI person. If you’re a developer, you can just rock up to a project and fix bugs, and if you follow the coding style they’ll probably get accepted.
If you want to successfully contribute as a UI person you have to convince a bunch of developers that you know what they should be doing better than they do. It basically never happens.
It’s all just the new testament. Before you fuck with poor people and nail them to a cross, make sure they aren’t just slumming it, and actually have a very powerful father.
