This is a live stream from the conference. All of the keynote speeches and all of the panels are being streamed. You can see the dates and times here.
If there is nothing visible here then nothing is currently being streamed.
Participating on the web
If you wish to participate in a conference session from the web you need a Twitter account.
The panels all have a moderator, who is watching a computer screen while moderating. The computer screen is showing a constantly updating stream of tweets from Twitter. These tweets should all include the hashtag #delhel.
Part of the moderator’s job is to feed comments and questions from the web participants back into the auditorium. If you want to pose a question, make a comment or suggest a relevant link please tweet it during the session.
Hashtag for participating
In case you missed it buried in the paragraph above, the hashtag for participating in the online sessions is #delhel. Use it wisely
