It's impressive for the project to have come so far. Between the oversimplified, hyper-opinionated GNOME, the rock-solid but dull and minimal XFCE, the nostalgic MATE, and whatever Enlightenment is doing these days, it’s nice to have a continually polished, modern, well-integrated yet customisable experience like KDE, even today. And save for Akonadi (which just never seems to work reliably, rendering software like KMail useless), it’s been a pretty stable one for me, too. Here’s to another 30 years!
My first love was WindowMaker :)
