Yes, this is the derivative sense of "meme", but it still says something important about cultural evolution in the information age. By Julia Mitelman.
This emergent phenomenon of belonging, participation and empathic sharing via parody and remixing may be the foundation of a new global community.
My take on Memes on social networks: Ideas, in written form, that can be tested, criticized, corrected, altered, and shared with others with common or conflicting ideas. It enables time to think, reflect, compare and contrast ideas over time, with others who either share one idea or add another perspective, thus changing the idea. An idea can be expressed in different methods, especially satire, cartoons, prose, poetry, self awareness and other awareness. They act a bit like taxonomy, not of organisms, but of ideas. They grow, develop, branch, and become something other than or different than or better than the original idea. Like factals, they self-replicate and mutate and respond to outside influences.
I can't count how many times I have changed positions after posting or responding to an idea. It creates adventure and excitement as an idea evaporates as new information changes its direction or makes the idea more powerful.
