You have the "Thumbs Up" implemented and that is cool, but if you are going to put the positive on there, you need to have a negative one as well. You may think that just having a 1 or 2 next to the +1/Up Arrow thing is enough, but it is not. That just means that people skipped it or had no other option. If you have a post with 3 positives and 40 negatives, it paints a much bigger picture of what the general consensus is of a comment. I know that it is the norm to only have positive options these days, but just because something appears to be negative does mean that it actually is. Other than that, I am enjoying the product you are making and I hope to see more good things in the near future.
