Hello,

I would like to get feedback from webmasters who experienced huge drop in traffic because of these (caffeine) changes. We lost almost 40.000 daily visitors.
Site is well established and quite old with lot of natutural backlinks, online since 2004.
What do you think ? Are these changes temporary or permanent ?
