Do digital poetry has to use classical forms, since it has a lot of its own means of expression, which could be used for narration on their own.
The user interface can be a mean of narration too!
Seeing that the classical poetry may describe and praise things as noble (or as trivial) as love, why digital poetry should not do alike?
The question remains, should such simple programmers' toys be still called “the poetry”. Maybe not yet? But since contemporary art used to deem that everythng could be art, if only an artist do call it art, then so:
Hereby I call this script “a poem”!
Has become, it is!
