Lesson from IKEA: advert using Facebook

Maybe some of you has seen this video,
For those of you who hasn’t,

Watch this video.

IKEA smartly use Facebook to make people as their ambassador, and willing  to promote the product to their friends.

Personally, I’m using Facebook and Twitter to promote this blog… with facebook URL share and hashtag &  retweeting on Twitter, the hit of this blog is quite awesome (with minor(none) effort to advertise)

What else can we do using this social networking awesome ? ^_^
