Today I "tweeted" about biomimicry and material culture as I was preparing to teach a class. Within a minute, I was being "followed" by someone I've never met, simply, it seems, due to the use of the word "biomimicry".
Out of curiousity, I tweeted "socrates, somnabulate, zygomorphic, jeroboam". So far no follows. Damn, now those are some interesting topics!
