The Deletionist is a Javascript bookmarklet that reformats any standard web page into an erasure—an abstract poetical form which removes selections of a source text.

It is a fun way to inject a little poetics into your web browsing foray or to find that kernel of fnord you don't really know is there.

Works best with text-heavy sites like archive.org or e2. Here's part of Carmen Bliss's Behind the Arras, deleted: 

eyes on

footsteps on 

the crazy 

somewhere on

and here's part of Robert Blackwell's Original acrostics on all the states and presidents of the United States, and various other subjects, religious, political, and personal

The Deletionist is a collaborative effort between the poet Amaranth Borsuk, the programmer Jesper Juul, and the programmer/poet Nick Montfort.
