Reviews & Comments of Perma.cc chrome extension

I do historical research for my church, among my various interests, and I find that Perma.cc is very useful not only in being able to go back to the exact information I cited, but also for allowing me to track changes in a website I'm using to practice my webdesign skills with which is helpful for those times when I feel like I'm not making any progress with regards to my coding skills and need a visual aid to remind me how far I've come.
