I find the pilcrows don’t work very well when used to write Pandoc without some further graphical editing. It just shows that it’s not the letter P of that font. If we’d want to use the pilcrow as part of a wordmark, some qualified person will probably need to do some designing.
Speaking of which, the pandoc website could probably also use a graphical update. Not saying the current state of things is bad, but if we are going to have an official logo, might as well do it properly, with something resembling a visual identify to go along with. Nothing fancy, but something consistent and with proper spacing etc. that’s less historically grown than the current website.
P.S. I know open source projects are known to struggle with design work (probably because it requires skills so different to programming? I don't know...) As a commandline-tool/library, pandoc so far didn't have the need for it at all...
