We're trying to focus on improving the website and business developement. The website looks ok on tablets when using a browser. There are no webdesigners, print designers or bloggers/webmasters who are using tablets as their primary device, so, without a real demand there's no need for supply. Also, at this moment, it would be pretty hard for contributors to edit and submit thei works using a tablet, with or without an application.
However, the changes are fast in this industry, and if we'll notice an opportunity in this area, we will develop dedicated applications for sure
