I thought these four posts from December 2010 at the website for the Q Gathering were worth sharing.
Ten Most Significant Cultural Trends of the Last Decade by Andy Crouch
Crouch is always good. Having been a trend watcher, author, and thinker since his re:generation quarterly days, there is no one better on this stuff.
My other favorite culture watcher is Alan Jacobs, an English professor at Wheaton College. I love his Tumblr account: more than 95 theses where he gives you clippings of stuff he found worth reading and he gives a few comments afterward.
Ten Most Praiseworthy Albums of the Last Decade by Josh Jackson
I don't know much about music but this is all the more reason to check out what Jackson recommends here and either order the albums, get them at the public library, or try them in Pandora.com or Grooveshark.com
Ten Most Transcendent Films of the Last Decade by Brett McCraken
See also the Best-of Lists at Christianity Today Movies (which McCraken contributes to).
Ten Most Beautiful Books I Read During the Last Decade by Margaret Feinberg
This is a much harder category because there are many great books but Feinberg picks some good ones here.
For years I have mining Eugene Peterson's recommendations on what to read in his Take and Read.
