It's neither more nor less practical in general. It's less practical for your company. It depends on what you're trying to accomplish. If your goal is to build a low-friction library for others to adopt (e.g. JQuery), it's a horrible, horrible license. If you're trying to build an ecosystem around an end-user tool (e.g. I'm making a web-based competitor to Adobe Illustrator), it can be an awesome license. Lots of open source tools aren't intended to be integrated into other systems, but used stand-alone. That's where licenses like the AGPL really shine.
