Comment on Feedback thread

Thanks for the feedback! This issue of duplicated commenter photos should now be fixed 😊

I have a general philosophy that all coding problems should have an elegant solution, otherwise I'm probably solving it poorly. Researching an elegant way to handle this was hard  because I didn't know how to describe the problem. But, I have learned that this solution can generally be described as "eliminating consecutive duplicates", and there is an elegant solution for it in Ruby!
