The poem is the original text, said Carol Ann Duffy, the poet laureate, in an interview with The Guardian. Just as with texting, in poetry you can "say more with less" and "it allows feelings and ideas to travel big distances in a very condensed form".
The Guardian challenged its readers to pen a verse or two about a story in the news in textspeak. Some of their efforts are in the comments here.
I reprinted a couple of text poems in this old post.
