Did you know…
… that the Real Favicon Generator site will spit out a package of properly formatted favicons and icons for you? And that it can take .svg files created in Inkscape as input? Nice.
… that Ctrl-R in Chrome refreshes a page, but Ctrl-Shift-R in Chrome will refresh the page but ignore any cached data? This is useful if someone (cough cough not me) were to upload a beautiful favicon and Chrome seems to keep using the old one no matter what.
