Scoop It or Not to Scoop it

Scoop it was one of the first Web 2.0 sites that caught my eye.  After exploring articles in my content area, mathematics, I thought it would be a great tool for the classroom.  However, after I evaluated the site with the rubric, I found the site to only score a 22 out of a possible 32 points.  The site does not adhere to the CIPA or COPPA laws, which makes this very difficult to allow students to use this in the classroom.  Their are inappropriate ads and pictures that show up when searching and it is clearly stated under their privacy policy that children under the age of 13 should not use the site and children under the age of 18 should be monitored. 
I did  enjoy the fact that I could share my scoop through Facebook, Twitter or Google.  The site is very easy to navigate through, its always available and the cost is free for individual use.  Overall I think I could use the site in my lesson or share it with my students, but I do not think it is appropriate for students to use in the classroom.
