Hesitate before you launch a hashtag. The experiences of President Obama and Catholic priests prove the point this week as competing views from church and state made hash of their original Twitter intentions.

President Obama, riding the topic of rising student loan interest rates, announced a hashtag for collegians to lobby Congress: #dontdoublemyrate.

Conservatives switched that up in a hurry -- using that very hashtag to complain about gas prices and unemployment or to lay the blame for the rate increase on the Democrats, according to The Washington Post.
