@alien, what I meant was, it's art. Some people aren't going to like it and I'm ok with that. I don't like a majority of what I see in museums, but I'm glad it's there and I'm glad I saw it. Sometimes it even grows on me. If we tried to show only art that made everyone happy, it would be probably be awful. And that's not the goal of Add-Art. If some people are challenged by what they see, then great! But they don't all have to like it.
Re: being U.S.-centric - the curators have the freedom to select what they find interesting. Given the traveling I've done in the past weeks, I would say, despite your personal opinion, this election seems to be of interest around the world.
And as you already know, if you don't like the images, you're free to disable the plugin. You have a choice.
If you want to choose replacement images yourself, try http://www.prowebsurfer.com/ We're working on a feature that would allow users to select various curated art feeds, but we're not there yet. If you want to work on development you can submit patches to me.
