Hi M...looks like you can "tweet" right from our forums here....look at the left side of the page...."tweets!"
I though this article (see the link below) was interesting...especially on the matter of Twitter & FaceBook:
"Some airlines say that social-media outlets, such as Twitter and Facebook, are beginning to disrupt the cycle. Some airlines are sending sales out directly to customers at all hours, making pricing far less predictable each day. Or carriers may tweet an hour-long sale. As a result, airlines can match competitors more nimbly, sneak sales under the radar of competitors and send deeply discounted offers anytime to customers who sign up for fare alerts.
So far, social-media sales still account for a small number of seats actually sold, but give it time."

I did managed to grab a JetBlue cheap fare as a result of seeing a tweet.
In my opinion, Luxury Link appears to favor Facebook over Twitter. Why do I say that? I notice frequently, tweets from LL direct participants to check the Luxury Link Facebook page regarding contests. I don't have a Facebook page and really have no interest in developing a Facebook following. I simply don't trust Facebook. So, as a faithful member of Twitter and a followers of LL on Twitter, I guess I am resigned to miss out on these contests.
