If you haven't gotten into the trend of "Facebooking your food" yet, good for you.  It's when you take pictures of your dinner at restaurants, then post the photos to Facebook or Twitter, where pretty much NO ONE CARES.  But if you ARE into it, we've got a few tips to make it a little less annoying for everyone else in the restaurant.  Here are three rules you should always follow.

#1.)  Don't Use a Flash.  You don't want to light up the whole place with it.  Especially if it's a nice place that's small and dimly lit.  And unless you have a really old camera, you probably don't need a flash anyway.  In general, pictures of food look better without one.

#2.)  Make It Fast.  Don't take ten pictures so you have a bunch to choose from.  It gives the people at nearby tables a chance to notice it and get annoyed.  Instead, take one or two, then put the camera away, at least until dessert.

#3.)  Don't Do Anything Else That Might Ruin the Atmosphere.  For example, don't take a series of self-shot photos of you eating, and don't stand up to get a better angle of your plate.  Also, if you just HAVE to post the picture on Facebook during dinner, at least don't sit there the rest of the meal checking your smartphone every five minutes to see if anyone commented.  (They almost definitely DIDN'T.)
