I appreciate the acknowledgement ^_^. It's been a dope team effort sharing all the info and helping each other out.
If I may share mine, in the "JPEG Compression too extreme" thread, @CyndiFoster you actually beat me to responding to someone's concern about an image's DPI. I typed it all out and boom your reply came in.
Here's what I wrote, then deleted:
"Good to note.
In web-based uploads, You mostly ignore DPI and PPI (Dots/Pixels per inch). Reason being is that the upload parameters on this site are pixel-based, so an 940 pixel image at 72 DPI will appear exactly the same as a 940 pixel at 300 DPI.
DPI matters most when printing. At that point, 300 DPI fits more than x3 the amount of information as a 72 DPI within the same inch of graphic."
But then you wrote your piece, so I'm like "nevermind" ^_^;
