Steem comment plugin API for other websites

So many web pages out there have comments at the bottom provided by i.e. Facebook, Google, Disqus, Twitter, or others.

Imagine if STEEM had an API that other websites could use. Steem would be everywhere. ( @xeroc wrote an article about a full-node API here, but I think most web developers aren't going to jump through those hoops to add comments to their page )

Just my 2 cents.
