Blogger Doesn't Support Trackback

This site is being powered by Blogger (a Google product) and I noticed today that Blogger doesn't support trackbacks. Trackbacks, if you don't know, are an innovative way to link to posts on other blogs. Say, for example, you read a blog post somewhere that sparked an idea that you would like to write about. Instead of posting a long comment on the original blog you post on your own blog, use the trackback link and a link to your post automatically appears on the original blog.

The benefits are obvious: networking and blog growth, driving traffic, raising content value for both sites, etc. Blogger has a trackback-like feature called Backlinks, but this is specific to Blogger, so I can't 'backlink' or 'trackback' to blogs outside the Blogger network.

Why can't I use trackbacks? Seems silly to me, Google.
