"Hack" as in "Hacker" rather than in "that writer is such a hack". Sorry for the ambiguity. :-) Although speaking as a poet, poetry is absolutely a hack genre, and so's magical realism and travel writing. Poetry: uses line breaks to create tension within individual sentences using enjambment, creates a visual structure that helps guide the reader from line to line, stanza to stanza. Magical realism: similar to surrealism in that it breaks the confines of reality to make a deeper, "truer" statement. Travel writing: literally hacks the world by creating a map of information (if you meant travel guides) and emotion (if you meant travel literature) which connects with the world around it. A way of bringing people to the rest of the world without the cost of gas/plane tickets/a horse/oxen.
