I agree with you, I believe .ca has hugh potential also. Just sometime's I feel as though I'm the only one that thinks so. You never really see any big sales of the .ca names.
It seems more people think .be domains have potential. I don't get it.
.ca has more than double the population base and it doesn't make sense to me that an English language .ca name would be less valuable somehow than an English language .be when the languages in Belgium are Dutch and Flemmish.
