For all the people asking whether or not it is exactly a thousand words or only more or less than that, I think it is very plain from the content. For example:

> "Write 1,000 words about it"

> "you are writing the definitive 1,000 words for this photo. Make them count."

> "Does it have to be 1,000 words? Yes...Your entry must be exactly 1,000 words"

It also says that the prize is $1,000, and there's 1 picture - but I haven't seen anyone asking whether each of those is an upper or lower bound!
