I always found the Arch community helpful, but slow in response times; the greatest community I ever experienced was the old Ubuntu Forums... [bias]we were awesome[/bias].
I've bounced from Ubuntu (Warty was my first) to Fedora, back to Ubuntu, to openSUSE, to Debian, back (again) to Ubuntu, through Mint, Arch, Manjaro, etc. I stumbled across Solus and really liked the philosophy
behind it and it's new approach to Linux.
I, too, acknowledge the mass of easily available-to-install software is lacking; however, it's refreshing to try out a new spin on Linux!
