python apps are not officially supported by Heroku, Looks like python app support is added for Facebook Apps to run on Heroku? (http://www.heroku.com/facebook)
I agree. The GTK font looks big. The button color and the GTK app color is not matching well. Giving same color to Title bar and menu bar is not a good Idea IMO.
But I feel, the new look is better than the previous default brownish theme.
Like the new logo of ubuntu. The font is minimal & elegant.
However, heroku.com says "Run Anything" :)
