If you want to register a complaint with the Obama Administration, it's probably best you air your grievances without directly tagging them in your Tweet.
Unless, of course, you'd like your Tweet logged, preserved and archived for posterity in a searchable database the White House will use to tag Twitter users who make routine comments that are "concerning" to the powers that be.
Case in point? After Barack Obama belatedly joined Twitter on Monday — in his official, presidential capacity — dozens of Twitter denizens began tweeting him sex jokes, threats and other unprintable inanities. (We counted nearly 500 tweets dropping f-bombs at POTUS in the past day.)
