i think, "spread" has many good potencial: spreading something, like torrent, video, goods, anything.
so not need to change the name.
Absolutely.
Also we already own spreadcointalk.org/net/com and spreadcoin.info/us,
and github.com/spreadcoin
and facebook.com/spreadcoin
etc
etc
it goes on and on.
Spreadcoin is a wonderful name and it would be a pain in the ass to change the name,
not just because we would need to come up with a new meme and new wording,
we would also have to register all the domains, which can be impossible if the name is too short or too known.
So IMHO it's out of the question to even think about a name change.
