Stratospherically

It is no coincidence that when chefs Bocuse and Vergé organised a stratospherically expensive Mediterranean cruise […] they called on the skills of their friend Lenôtre to produce Bocuse's legendary truffle soup.

Being forgotten is the fate of most SCP Foundation employees, due only in part to the invisibility of their work. At Site-43, where the community is close-knit, the staffbase relatively humane, and a well-trafficked hallway is set aside for portraits of past local notables, the problem is somewhat attenuated. But memeticists, countermemeticists and antimemeticists face high, very high, and stratospherically high odds, respectively, of being forgotten while they're still around. Amnestic effects have a way of rubbing off on you over time, and there are enough identophagic, obfuscatory or predatorily erasive entities dwelling at the edge of perception that every bit of visual reinforcement helps to underline one's continued existence.
