How popular is OpenSuse Tumbleweed distribution?

I have been using an Arch-based rolling release distro for two years. I only recently installed OpenSuse Tumbleweed, I used Suse a long time ago. Both distributions are similar in that they are based on a rolling release model. That’s why I’m interested in how popular Tumbleweed is here in the community.

It’s always hard to measure.

There are many “Tumbleweed” threads at the forum, and that suggests it is pretty popular.
