Neofetch is a small, little nifty program which is petty much useless but very good for one specific reason:

Neofetch is very good for when you wanna brag about your Linux distro and your hardware. For example now everybody will see that I’m on super chic Manjaro, a very up-to date Linux kernel, that my beefy AMD Ryzen machine is running since almost 5 days and that I have 32GB of RAM available. Just for maintaining my silly bloggo. π Kool, eh?
You impressed now?
