On the new “MacVoices” (http://www.macvoices.com), Marco Arment is “the guy who does everything for Instapaper,” talks about the origins of Instapaper.

He reveals his method of beta-testing, explains why graphics aren’t included in Instapaper-processed articles, and what drove his feature set and pricing decisions for the two versions of the program. Arment also discusses his iPad expectations, and why he thinks it will be important to have an iPad-native version of Instapaper available as soon as possible.

“MacVoices” is an Internet show and podcast that delivers in-depth discussions with the most influential people in the Mac industry, as well as “the individuals who are out there making it happen on the front lines of the global Apple community,” according to host Chuck Joiner.
