This post seems lighthearted and not mean-spirited. I do wish they said "awesome" or "great" instead of "the best," but they're not trashing other distros and it is relevant so I don't see the problem.
At least it's those positive things. From the influx of newcomers here, I just hate that they see posts like this before than can objectively see the field for the trees.
If this entire sub becomes "OMG THIS IS THE BEST", it's going to be nothing but noise real fucking fast.
I would normally 100% agree with you. But if it's an underrated distro, then I tend to be more lean on this. However, I agree that OP should have done a better job at 'advertising' openSUSE. For example; not mentioning YaST is just criminal.
I definitely hope that the noise ration will improve (by the amount of noise decreasing) over time. But, as it stands, the community is still relatively small. I get your grievances, but I honestly don't know what the best set of directives would be.
