Today I tried MANY of the suggested sites for Thing 40.
For MUSIC, I enjoyed searching and saving selections in Pandora.FM. The link for Splice did not work.
For BOOKS, I checked all of the sites listed.
For SOCIAL, I did an account for Ping.fm. It is good to be able to combine account information for Facebook, Delicious and Twitter. I also tried the Lunchbox and Wheel of Food sites. These sites are more useful when using a zip code such as 55423 in the Twin Cities area rather than our local rural zip code which yields no results. As I have not had lunch yet, thinking of the food sites makes me hungry!
Of the PHOTO/FLICKR sites, my favorite is Interestingness. I had fun doing random views of the photos.
For the VIDEO sites, I enjoyed TimeTube where I used Supreme Court as a search topic and now have a reminder when it is updated.
For GOOGLE, I did a search for a neighborhood under Walkable.
Being I had used Big Huge Labs before, I tried new mashup options, and posted a simple Palyvore fashion one below:
