Just curious...because you told Lifehacker.com in September 2010 that you'd follow up with a Linux version after the Windows version: http://lifehacker.com/5650137/blio-is-a-fast-feature-rich-and-free-ebook-reader
I for one, really like the way it works in Windows but use Linux most of the time. I'd be more than happy to test drive any alpha/beta you have.
We are not currently working on a Linux (or OSX) version of the Blio app. We are investigating a web-based version of the app that would allow for Linux, Mac, WebOS, and Chromebook users to be able to use the app on their laptops/PCs.
