If you read my comment history, you'll find I'm pretty knowledgeable about software in general and FOSS in particular. I only lightly use Office applications, and I had no idea OpenOffice was dead until I saw this thing called LibreOffice in my distro a few years back and was like "WTF happened to my OpenOffice?" and started Googling. So it's not just a problem for non-technical users -- keeping track of when software you don't use on a daily basis becomes obsolete is a problem faced by everyone.
