Do not really know too many in Germany yet although here are some that I know are quite good in that country:

iGoogle, blinklist, netslektor, roadster, yigg.net, snaqit

In France, you can find some of the English ones in a French version like Delicious or Digg that are quite popular, but here are some of others:

I also know that specific social bookmarks get more and more developed now and you can come across with some dealing with precise topics such like Connotea, a French social bookmark focused on scientific news and with scientific users!!

Let me know if you know some others..
