Do We Need To “Save” More Words?

I found SaveTheWords.org which lists uncommonly used words.  If you select one of the words it defines the word and allows you to adopt it meaning you “hereby promise to use the word, in conversation and correspondence, as frequently as possible to the very best of my ability”.  I like the site and I love learning in general, but the site got me thinking that if you need to define the words to 99% of the people you communicate to, do we “need” to save them?

If I use a word like coquinate, mulomedic, or algotrophy I may seem more intelligent, but if you need to lookup the meaning are we asking that society save (and learn) a set of words we we don’t need to communicate efficiently? Language can be a beautiful thing.  Shakespeare and many others have taught us language is an art form but language constantly evolves.  If you look at how youth in the world communicate it is short, abbreviated, and to the point.  Are we better communicators for using less words, or should we save coquinate, mulomedic, and mulomedic?

I like to think we have a brilliant community who frequents this site so if you have a thought on this, let me know what you think!
