I just added Townsquare to my site today

Townsquare was released 10 days ago: 6/19 Instead of feeling like you're reading alone, this is a tiny presence layer so that when people are reading the same blog post, they can see others and know who's reading. It's like a chatroom combined with manga. The conversations are saved in the backend of the official site. And displayed on my website. I'm learning more and intend to gradually self-host. This is a real-time chat on the website and can disappear after the reader leaves. There is a discussion topic on Hacker News.
