Would anyone be willing to help me add improvements to the page? It's become popular more quickly than I expected, and I would appreciate the help. I've temporarily added my email address to my hacker news profile, so anyone can contact me. Thank you!
Reversing the list (last-on-top) and putting the "More names belong here" text above the fold might be a good idea.
And if you know somebody who can draw icons, getting an icon for each "refrainment" might look nice (might also look worse, but good icons in the CC style could spread in the community and be used e.g. on researcher's blogs).
Otherwise, I like it. It's clear, simple and to the point.
Also, I think you should default the subject to empty and mandate it, you seem to have a lot of mathematicians (though it could be because it spread there first).
And you should check your form's encoding, there's mojibake at the end of the list, "Université" instead of "Université".
Linking to the recent NY Times and blog posts from well-known researchers would help as well.
