Thing 11 - Social Media

I had fun with the "Liar, liar, pants on fire" story about a boy's iTouch catching fire in his pocket. I am sure this has to do with the battery manufacturer and not with Apple, so I suppose they aren't going to be able to get money out of APple for this lawsuit.
I use Stumble Upon because when I have the time to surf the web I like to be amused... the Stumble button sits in my browser and, when bored, all I have to do is click... and some picture, video, story or amusing story it brought to me instantaneously. If I don't like it, I click again.. but I can (and do) customize my preferences so now I only get stuff I like. I'd a great boredom buster, but, let's face it... who has time for this?
I like to go directly to CNN or NYT or pull news in my cellphone when I want to hear news. I don't particularly want to read weird stories from all around the world, so I find Mixx a bit awkward to use. What other people like to read is not necessarily what I want to see in my front page. I prefer to start with international news and move to local, sports being at the bottom of my reading pile.
So, no, mostly I wouldn't use these pages and, if anything, I'd like to have links to "mail this to a friend" on regular news sites so I can share with particular people. This social tagging concept is interesting to see who likes what and may be useful to somebody in advertising or journalism, but I can't see any application to my classes in the media center.
I have run across some pictures and flash animations using Stumble Upon that I have enjoyed: the program keeps a list of my favorite sites so I can always revisit them. But, again, this is mostly for personal use and I can't think of uses for other purposes. Perhaps I should read other NEFLIN blogs to get further ideas for using this in instructional situations.
