Hey man, how's that virtual anti-mass spectrometer coming along? I know some people have said that your development of the software might cause a resonance cascade, but I'm pretty sure they don't know what they're talking about.
I like how we're all not touching this. It's like someone took a dump right in the middle of the room and we're all just staring at it and each other and accepting it and hating it.
