Do you know how many ways you can keep up with LISNews outside the paradigm of a browser? There is an e-mail digest of posts you can subscribe to if you so choose. Thanks to the magic of Twitter and SMS short codes, you can get updates sent to your mobile device as text messages when new posts are made. You don't even need to be a registered user of Twitter to do this. To get updates on your phone, send the following to 40404: FOLLOW lisnews For readers outside the United States, a list of codes to send that command to can be found here. RSS can give you feeds in an appropriate reader. Plugging http://lisnews.org/rss.xml into your RSS reader will let you receive posts outside the browser. A variety of feed readers are available and we can recommend tools like liferea and newsbeuter. If you have a Kindle, you can also receive LISNews posts by way of the magic transport layer known as WhisperSync. Access via Amazon is available at a nominal cost. Nobody will see any revenue from that before the heat death of the universe. If clicking around in a browser isn't your favored starting point, other avenues do exist to try.
