Tracing "Blip Depth" in Google Wave

As Paul and I continue to work on prototypes and ideas for using Google Wave to trace collaborative knowledge work in the classroom (more on that here), we've intensified discussions of typical user practices within Wave. As part of these discussions, we've run into some interesting issues surrounding how we simply describe—even amongst each other—certain kinds of user interactions and how they're reflected in Wave.

At a very basic level, we're running into issues of terminology that are still amorphous, since the community of users and developers interested in Wave is likewise nascent and developing. This is an issue of representation, really.

For example, Paul and Ian (one of our tremendous student researchers) have been working on a robot participant that collects data about collaborative work in a given wave. But one of Wave's affordances is the ability for multiple participants to edit a single blip, or to create a series of nested replies within a higher, "top level" blip. This makes data collection a little more difficult.

These kinds of contributions are harder to collect, creating challenges for the software architecture of the robot participant and it's data representations. But they also create challenges for terminology; what do we call these kinds of user contributions?

Yesterday, Paul started a new blip within one of our existing waves for this project:

Paul goes on to offer two likely solutions to the problem of "blip depth"—one of which involves creating a tree structure of the entire wave and storing that information in AppEngine.

But as Paul and Ian continue to delight me with ingenious solutions to development challenges, I'm even more interested in Paul's brilliant term for representing the kinds of data we expect and dearly need to surface and trace. "Blip depth" says it all...

Google Wave :: First Impressions

As someone who's been eagerly anticipating the initial public rollout of Google Wave, I waited with much anxiety and baited breath as the distribution of invites were pushed later and later into the evening of 9/30. I went to bed still hopeful, and awoke early to see my invite on 10/1.

Unfortunately, I didn't have a great deal of time to work in Wave yesterday, but I started to get some interesting things done with the platform this morning. I've embedded a screencast below which details some of the basics and some first impressions of the service.

Rule #1 of Wave: find people to wave with. No contacts on Wave is probably akin to being the first person with a Compuserve email address.

:: Update ::

Things are really moving fast in Wave, now that the contact list is growing. I've added a brief screencast to provide some insights into realtime public collaboration within Wave:
