Esperanto is due for a second explosion I think, especially due to the internet that will connect other idealists like me.
Esperanto saw an explosion between the two world wars, but with Soviet and Nazi crackdown, as well as CPC crackdown on it in China (another place that saw Esperanto flourish) its growth was stunted.
I do have a hope that as far as linguistic awareness goes, things will be better with my generation.
