Initially I thought it was a server-side issue, but now it's all clear that my favorite (until I read about their copyright issues) e-book reader Genius PDF is out of existence. Further look-up reveals that everything about this app and its creators is deliberately wiped out from the internet.
About Genius PDF
Genius PDF, originally based on Sumatra PDF (better call it a rip-off) , was probably the best PDF reader for Windows. The lightweight Genius PDF made 'giant' Adobe Reader like apps feel waste as it didn't only support PDF documents, but could also read .CBR/.CBZ comics files, .DJVU documents and all other e-book formats like .epub, .mobi, .fb2. This is not the end of the features of Genius PDF. It was a superb alternative of Adobe Acrobat too, as it supported pdf conversion of any printable document from Windows. And the best of all, it was free!
LiquidPsi Software were the creators of Genius PDF and they launched the last important update to this Windows only application in December 2013. Their own site liquidpsi.com disappeared suddenly in January 2014. And then the app site, geniuspdf.com. Then it was turn of their twitter account, @geniuspdf, which was deleted soon after. Now the situation is that, each and every information about LiquidPsi and Genius PDF is deleted, whether it is their sites, blogs, Twitter, Facebook page, Google+ page.
Effects on Application
Since the app works totally offline, there will be no direct consequences on it. Genius PDF will continue working normally, as it did. The downside comes from the security point of view. As the file-host is down, no updates are expected in near future and there may arise security concerns to the app. It's already full-featured, therefore they should not be any issues of feature-lacking.
The question arises here. Why Genius PDF disappeared along with its developers? Most possibly, it's connected with the treatment developers of SumatraPDF gave to Genius PDF. Read more about it here.
