I've noticed that Facebook tends to embed Wiki pages as a description
for certain pages (like for Cities).

In searching, I have a found a very few references to others being
able to do this, and they refer to mediawiki.org. But I haven't been
able to find any further information on how to do this.

Have you guys ever tried to do this? Can you point me in the right
direction to start?
