@Rassilon: Thanks a lot for the testing!
About the own RSS Feeds: send me the feeds you would like to have (just like the two you mentioned but with direct links) and i get in contact with them to ask for permission.
I want to ask because that makes it easier for me to use their
logos and branding.
I just want to clear out copyright issues.

About the spinning wheel: for some cache reason, the browser
sometimes needs a second refresh. So simply refresh your web
browser and it should work then. i will try to find a better solution
for that but flash realy sucks at this moment
