Wed update: Free chicken biscuits, how to hide yourself on Foursquare, and I’m going to the IBC tonight!

Memphis-area Chick-Fil-A stores are giving away free spicy chicken biscuits all day today. A portion of proceeds from today’s sales will benefit MIFA, so stop by. Free food? Wonder if the Nuh-Uh Girl will show up.

Last night several of us who were checked into Foursquare at Kooky Canuck were wondering, “How do we NOT show up when someone searches for a particular venue on Foursquare to see who’s here?” Here’s the answer: Go to http://foursquare.com/settings and under “Your privacy profile,” uncheck the box named “Show me in the ‘Who’s here’ list in the mobile app.” Your Foursquare friends will still see you when they look to see who’s at a venue, but those with whom you are not friends will not. If you need to remove someone as a friend so you will not show up in their venue searches, do it at http://foursquare.com/manage/friends. Keep in mind that if you tweet your checkin, they will still be able to see it if they follow you on Twitter, so you might want to turn off the “send to Twitter” button in those cases.

Tonight I’ll be doing $10 wristband night for the International Blues Challenge quarterfinals. The wristband gets you in 19 clubs to hear blues bands from around the world. It’s a two-block-long buffet of music! Memphis is so fortunate to have the IBC… come on down and take advantage of what your city has to offer!
