God. If you basement-dwellers spent half your actually researching or doing shit instead of yammering on about things you think you know, the world would be a better way.
Gaping security hole? Find me one fucking example. Just one. I'll wait.
Unsigned packages? Find me one fucking example where this has bitten someone.
Not ready for serious systems? Check the top news article on archlinux.org. Oh cool, real package signing with GPG.
Ah, well-documented and sensible like Slackware? Well, Slack *is* both of those things. Now, can you enumerate the reasons why Arch isn't, or is this just more unsubstantiated, unsolicited opinion? From the sentiment on the Internets, it sounds like Arch has some of the best docs out there.
Go here and tell me what #2 is on the list. Is it Slack?

Seriously, if you don't like it, that's fucking awesome. Keep using Ubuntu - it's good too. But find a new hobby that isn't bashing things you don't understand. Or at least do some fucking research. It will add some credit to your yammering.
Out.
