I can confirm too. A few months ago when Facebook pushed to convert everybody's "likes & interests" into "Like <page>" things, I initially agreed to it, to see what happened. What started happening was that my News Feed began to fill up with spammy events/messages being pushed out from all the things I Like-d. Bands, movies, books, TV shows, etc. The problem was it became much harder to see "real" events/activities from the people I was connected to, friends and coworkers, etc. So I went in and de-Liked all of it.
