First off, I have to thank
xarrion for my invite to Google Wave. Since he's done that, I've found my Firefox tab list is just growing and growing with useful bots and general purpose silliness relating to Wave. Keeps me from getting alarmed about my diabetes or the fact I'm still off work. Hurrah! Something to distract me...
So why would you care about Wave?
1. Play by e-mail/chat/IM gaming. Wave is a cross-road where e-mail/chat/forum/IM intersect. The environment readily suggests use with things like Obsidian Portal or Epic Words with each wave corresponding to a game session. There are tools to let you publish waves to a blog for instant game summaries and document sharing within each eave is distinctly possible.
2. Event Organisation. Oh and how! There are already enough toys (map extensions, polls, yes/no/maybe lists) to make this process a lot smoother if you want to give this a go. Surprising it's not linked to Google Calendar or Remember The Milk but it's a matter of time I think.
3. Collaborative Research. Brainstorming, using common references and translation. There is plenty here if you want to work on a project that isn't necessarily tied to the previous two items. You know, that real life stuff we keep hearing about...
If you want functionality, you can find it here and I suspect this is where Google Wave is a big vote winner. Wave functionality isn't going to decrease any time soon and the number and quality of bots (automated scripts) will also increase. About the only thing that will hamstring this is if the number of duplicate bots become like other Google gadgets - one gram caviar to one kiloton of suet.
The other killer is whether people will pick up yet another web tool. We have a plethora of tools, in some cases more than enough. It may be that if you can use Google's API that you can devise a tool or extension that will give you virtual immortality. For the rest of us, it may need a bit more nous or the goodwill of another developer.
As I believe in paying forward, I'm going to offer an invite to the first three people who comment here with a reason for using it other than "Ooh! Me! Me!"
absintheskiss and
xarrion are exempt for obvious reasons.
