Hi. I point to pdfreaders.org to friends who uses Windows. One problem that has happened more than once is that the first reader that mentions Windows-support, Evince, had their last release for Windows around 5 years ago. The situation for Okular appears to be similar. I believe this is counter-productive: Windows users will try Evince, will fail to get it to work because the release is too old and not supported anymore, and will go away. When I point them directly towards SumatraPDF they are happy (until they want the "Print-To-PDF" feature). Would you consider dropping the "Windows" links for PDF readers that doesn't have supported Windows downloads? I think this would be an overall improvement to the site.
Thanks, /Simon
