Education/communication
Today's overarching issue: how ICANN educates and communicates. The organization had trouble telling people that new top level domains had been opened up (like .museum and .info) and so for years some web sites and applications that asked for email addresses rejected any TLD that wasn't com/net/org or a recognized country code.
Today during the public forum we heard from a lot of people who want better education/communication efforts. Registrants need to know about the risks of registering a domain name and not keeping their information up to date with a registrar — and might need to understand how the system works and what they're really getting when they register a name. Hardware manufacturers might want to know about IPv6 and that they'd save effort/money by dealing with it now rather than waiting for later. Users might want to know about IDN and what it means. IANA might want to find a way to describe what it does so that people don't send them 13,000 emails a month complaining about things that IANA doesn't do.
Oh, and we also discussed .xxx. More about that tomorrow.
