The suite itself predates popular use of the Web by a handful of years and yet the community's size seems to have peaked long after its release. I've been able to trace an active Qbasic community all the way to 2011.
About three years later I get a hand-me-down Windows 95 machine with Qbasic on it, and I set out to make my own "operating system". This was actually a pretty popular thing to do at the time...here's an entire website full of 'em, where I published my own MS-DOS GUI as a teenager: http://qbasicgui.datacomponents.net/
Today, I do very well as a senior developer wearing multiple programming hats at my company and I'm close to cashing in some of that stock to develop my own video game. It all started with Qbasic.
I'm a senior cyber security engineer and also a polygot :) Video games sound more fun, I still make some in my free time.
