This past week we have been trying some new comments out. A lot of people have given me positive feedback about these comments, but we are still having some major issues with them. About 10% of our visitors can't even get the comments to load at all. At least for the time being we are switching back to Disqus. The possibility remains that we will once again try spot in the future, but not until we are sure we are completely compatible.
Sorry for the inconvenience of switching back and forth, Hopefully this won't be too annoying for most of you.
We did seem to get positive feedback about having media in the comments, so we are going to now enable that in Disqus.
