Over my 15 years of negotiating (poorly) the doots of both up and down flavors I've learned very few things. So few in fact that they fit in this very short list:
• A subset of users downvote bad grammar, typos, and mispellings misspellings regardless of the message.
• A subset of users wil downvote perceived negativity, even if the intent was ironic, regardless of the message.
• A subset of users will downvote overly verbose or indulgent posts, especially when they DON'T start with a tl;dr: summary, regardless of the message.
• A sunset of users will gravitationally collapse and ignite hydrogen fusion, and then pass beyond the horizon of a heavenly (or hellenly) body, regardless of their masses (as long as it's more than ~2.5×10²⁰ Earths' worth of people).
ntl;siri: hey thx!
