Opium joins McSweeney’s, Featherproof, and whoever else we are forgetting to mention in the category of “lit publications with iPhone apps”.

Todd Zuniga talked to Jacket Copy about his mags new use of technology.

JC: Is the Opium app addictive?
TZ: In a word: absolutely. Opium publishes fantastic, bite-sized gems every day (next week we’ll showcase 250-Word Bookmark Contest finalists — an estimated reading time no longer than one minute and 20 seconds). So there’ll always be something new to discover, along with the curated stories that lead things off. Also of note: According to the must-be-true source of Wikipedia, between 150,000 and 200,000 opiate addicts lived in the United States in the late 19th century. This app, if used properly, will triple that number.
