When I need to quote an SG address over the phone, it would save time and reduce errors if I had a domain with non-ambiguous pronunciation (0 vs. O, S as in Sam, etc.).
Also three characters would save even more time. I realize this isn't the most important issue, but over time, it would be very helpful. I checked with Network Solutions and, at the time of this post, there were several 3-character .ORG domains available.
Am I alone on this?
