As long as there's a community with members that talk amongst themselves, there will be diversity at least in accent or terminology.

That's the point I want to pick up on. Because of technology and other factors, such as ease of travel, there will come a time when we interact more with people outside of our (physical) community than we do with those inside. In that case, regional dialects will begin to become less important to our lives.

A major factor will be when voice is used more widely for our forums and such.
