I started using the hashtag, #SummerofUS about two months ago. For those of you who don't use twitter, a hashtag is used to keep track of a story or the progression of information on twitter. Type in the hashtag and you can see the most recent or most popular "tweets" with said hashtag. Usually it's something catchy or funny about the subject, and in it's best use, draws further attention to the story. That isn't at all what the #SummerofUS was meant to do. It was just an expression of my emotion about the upcoming summer.
