from www.aboutfoursquare.com – They always say that once the adult entertainment industry adopts a technology it’s bound for mainstream success. If that’s the case, maybe this offer is the pebble that will begin the avalanche for foursquare. Adult video star Tanya Tate was encouraging fans to check in with her at the Adult Entertainment Expo to receive a free promo item.

[Tate was signing autographs and posing for pictures at the Girlfriends Films booth. Tanya was also taking to popular social networking site Foursquare to boost traffic. Those that used their smartphones to “check in” with Tanya during the hours she was signing received a promo item from the sexy star.]

The Adult Entertainment Expo is held in Vegas each year on the weekend that coincides with CES. Tate appeared at the Girlfriends Films booth for photos and autographs.

“I wanted to add a little more fun to my Girlfriends Films signing,” said Tate. “So, of course, I turned to social networking. I think using it in this manner adds to the experience.”

British-born Tate is a rising star in the adult entertainment industry. She’s already won a Nightmoves Best MILF Performer award and has attained an AVN Award nomination for MILF Performer of the Year as well as an Xbiz Award nomination for Performer of the Year.
