Frankly, domain name itself, at this point, is similar.
Three things to remember:
- The algorithm is just trying to be human.
- That asked, have you ever recommend content to another human based on the ext or or domain name?
- Many browers are effective hiding the domain.ext. This wouldn't happen if real human users cared.
All that said, to me .org is typically a not-for-profit entity. Instead go with .co, .io, etc.
.co is a suitable alternative, if that were available?
