good website/ www.youtube.com
because you could find alomost everything you would want to learn or watch on thois website. You could look for music you like of movies that are going to come out great way to learn and watch it at the same time. What ever people think is cool they put on this site to show people. Thats whats sweet about youtube you could put anything on and anyone could put it on. they even have tv show like family guy, american got talent etc.

bad website/ www.facebook.com
because anyone could see what you have been up to in your life with the pictures and its no good people could steal your identaty because there is enough information to do so. there going to no who your friends are what they are writing to you about and its not personal even when you delete everything they still have it on there hard drive they still have the information about you.
