Symbaloo

I just signed up for Symbaloo and I am very excited.  I really needed this new bookmarking tool!  I had kind of given up on bookmarks and was just keeping them in different browsers.  Is this a tool I could have my 6th graders use for their bookmarks?  I am afraid they are going to want to apply it to their personal (non educational) network and not for learning related websites.  It may be helpful like in the video we watched from the student who created her personal learning environment.  Can I help them turn their personal into a learning network?
