Mariner Software has turned 20—quite an achievement for a software company that started out competing against Microsoft with Mariner Write and Mariner Calc. They’ve since added numerous more proprietary programs, such as Montage, StoryMill, and MacJournal. And this weekend, the majority of their Macintosh products on sale for 40% off.

Every now and again, it seems a software company sells you their product not just because they want your money, but because they’re genuinely interested in what you’ll do with it. I’ve always had that feeling with companies such as Toon Boom, Boinx and Corel (specifically with Painter). Now, add Mariner Software to that list, as they’ve just announced the launch of writerspub.com.
