You could use this technique to follow student blogs or blogs from any group or individual you wish to follow. I had offered to help participants set up their Google Readers hands-on to find all the posts in blogs that have been written to reflect on certain EVO sessions. But the participant mix took the conversation into other directions.
Here are the text chat windows we embedded to provide a backchannel to the live stream
We encountered a problem through choice of Sync.in. After 8 participants had joined the chat it would allow no more (and we were relying on that chat to disseminate the Hangout link on the fly). We didn't realize until 15 min. into the program that people could hear the stream but couldn't communicate with us or figure out how to join the hangout, but eventually stragglers made it in and informed us, so tweeted the Hangout link and put it up at http://learning2gether.pbworks.com and created the second TitanPad text chat below.
Plan B Text Chat
Significance of the event
There is another very interesting aspect of the session this Sunday. It was the first time I conducted such an event in a Hangout On Air, and streamed the video at http://webheadsinaction.org/live
This procedure overcomes two limitations of hangouts. One limitation is that you can only have 10 in a Hangout at a time. The other is that it's hard to tell people where you'll be hanging out because hangouts are designed to be found through your circles and other social features of Google + so there is no URL to give out until the Hangout actually starts. Thus, many Hangouts are announced, but participants can't enter because there are ten there already, and the participants are left standing outside a locked door, which is not colleaguial.
http://webheadsinaction.org/live overcomes both these problems. First, I can embed an Etherpad clone chat there where anyone can interact. I can put the hangout URL there and others can click on it and join the chat, or if you are having problems you can get help in the chat (in practice we ran up against the 8 participant limit in Sync.in, which we will avoid for this purpose in future). Secondly, since the YouTube embed that lets you play the recording later HAPPENS to stream the event while it's in session, then anyone can visit the URL where that link is embedded and listen to the stream. So if the Hangout is full, hundreds more can listen in and interact in the Titanpad chat (thousands? tens? no idea actually). We can also announce on the stream when places become available in the Hangout and participants in the Hangout can be rotated in and out that way.
So one purpose of the session will be to Learn2gether about Google Reader how to follow class sets of blogs. But in so doing we'll see how to stream a Hangout so it can reach beyond just the ten in the hangout itself.
Testing prior to the actual event
I tested this at around 1300 GMT with Kalyan Chattopadhyay.
It worked fine as you can see from this recording
(sorry for messing around setting up, but I was checking on other computers that the stream was being broadcast, when Kalyan responded to my call to verify that it was being broadcast worldwide )
