Interesting problems discussed - but even more interesting suggestions for improvements.
Many of these pain points can be improved with robots.
Invitations to a wave should be by URL, sent via email or instant messaging or any other means, and if Google Wave wants to make it easier, it should tie into your existing contact list.Google Wave shouldn't require an account for those invited to join a wave, and if someone wants to create an account, it should for now be associated with existing Google accounts, and not be entirely separate.For those who already use Gmail, Google should think about non-intrusive ways of integrating Google Wave into Gmail to eliminate the notification problem and create a bit more of a network effect. For those not using Gmail, email notification is a must.Though seeing people typing in real-time can be useful, the feature should be optional, to allow people to finish a thought before others reply or comment on it.The interface for switching between editing and replying needs to be both more obvious and faster, and the constant creation of inadvertent replies should be eliminated.Google Wave should remember if you have collapsed a blip and not show it again unless it gets new traffic, or even collapse replies after they're read, just like an email conversation in Gmail. There should also be a way of hiding all replies completely, so an edited document can be read without interruption.If Google Wave is to be useful for document collaboration, it has to be able to publish a wave to other formats and mediums, such as email, straight text, RTF, HTML, to a blog post, or to a content management system. Copy-and-paste is not an interface.Blips should be allowed to have user-defined metadata like completion status, task assignment, and due dates so Google Wave could become useful for task and project management.
