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!
