I've never understood why people even wanted to use this. For the styling? So you can just copy some random stuff from Twitter and it looks like Twitter but is also interactive?

Just with the Facebook like-Button, you're exposing your visitors to the tracking of Twitter.

For what? Just so you can quickly copy one snippet and be done with it, instead of manually copying author name, content and link and spending 10 seconds to format this yourself.

I wish I had something constructive to say, but this always seemed like a totally unnecessary "feature" with a lot of downsides. Instead of embedding 280 characters in your website you make it download an order of magnitude more from somewhere else and then execute code to display those characters in a way someone else deems appropriate.
