Some more name ideas for consideration which floated into my head while waking this morning.
For me, it can be the look and sound of a word that is the appeal, often spelt unconventionally to grab attention (and of course the correct font can be vital), as many orthodox spellings can sometimes lose their potency through ubiquity.
Btw, regarding the $ name award, have you considered the option of offering project tokens instead, or something similar – or a combination?
A list of names with .com taken but no traffic:
(Used GoDaddy to check domain availability - and price, where available - denoted as ($?) if no price given - and showing on Alexa.com as not enough data to rank.)
Project and/or token names
(I'm not sure tokens need domains, but a mix here of some that might be suitable as either tokens, project names or both)
Fibr ($?); Hyv ($?), Ouishare ($?) (Global rank > 31 million)
Tokens:
I like your “atoms”, but how about instead spelt ATMZ or ATMS, with a play on an ATM giving out cash? Another related could be quark(s), but spelt KWAAK(S) ($?)
Spells, Dust, Tap, Rad, Radz, Tingl
(Deriving from gift economy)
Pebbl ($?); Marbl, ($?); Beedz ($3k); Favr ($?); Fayva ($12.5k); Talnts ($?); Talntz ($?)
Video: MyScreen ($?)
Q&A: Solva (also a town in Wales)
Adult: Sensoria ($?) including a play on “censor” (an old Cabaret Voltaire song title)
