A refresher for those that need it http://en.wikipedia.org/wiki/Meme
Is Memematics covered in EP? Or something akin to it? The concept seemed all the rage years back (and was used extensively in "Transhuman Space") but seems to have fallen out of favor as of late in both the real world and games. Of course given the considerable technologies that Transhumanity have on hand I imagine there is plenty of ways to safeguard yourself from such mental clutter (and consequently, plenty of hacks out there to get in as well).
