Welcome to r/linux rants and experiences! This megathread is also to hear opinions from anyone just starting out with Linux or those that have used Linux (GNU or otherwise) for a long time.
Let us know what's annoying you, whats making you happy, or something that you want to get out to r/linux but didn't make the cut into a full post of it's own.
For those looking for certifications please use this megathread to ask about how to get certified whether it's for the business world or for your own satisfaction. Be sure to check out r/linuxadmin for more discussion in the SysAdmin world!
