Bookmarkr App- almost there!

To my own surprise- I had a lot of fun with this! I am having a hard time figuring out how to filter the index view by category... I will spend a little more time this weekend figuring that out. I also need to validate the url for HTTP(REGEX hell?) and show that a comment is favorited and has a comment...  I am confused about where to place the logic. Bootstrap is finally starting to make sense to me :)
