nice post, welcome to the indieweb! btw, it looks like you have the [webmention plugin](http://wordpress.org/plugins/webmention/) installed. if you also install the [semantic-linkbacks plugin](https://github.com/acegiak/Semantic-Linkbacks), or switch to [this bundle](http://wordpress.org/plugins/indieweb/), you’ll see the actual content of those comments (or labels for likes, retweets, etc. from the social networks).
i’ll also shamelessly plug http://brid.gy/; feel free to try it out!
