I have an idea how to promote Lojban.
I remember that I met Lojban for the first time in Wikipedia article about Genghis Khan:
http://en.wikipedia.org/wiki/Genghis_khan
I wondered which languages were also interested in Genghis Khan and then I saw a mysterious language called "Lojban". ........ That is how I am here. :)
The idea is, what if translate into Lojban or even create Lojban stubs for the most popular/edited English articles in Wikipedia?

(most popular pages are somewhat more difficult to find)
Let's start with George W. Bush ! :)
