I'm liveblogging Barack Obama's appearance on the second MySpace/MTV Presidential Dialogue, which begins momentarily, and in which Obama will respond to the top video on 10Questions.com.

2:32: It's over. I have no idea what it looked like. But it seems to have gone off well, and young voters were able to get a sustained dialogue happening with Obama.

2:30: Post-mortem: more people strongly agree with Obama now than at the beginning. Obama thinks that the key to his campaign is forums like this, because he feels that he comes across better this way rather than in the soundbite coverage in the news. Given the online component of this event, that's encouraging -- Obama does seem to understand the way the conversational nature of the web.

2:27: Colbert: Obama things it says something about the lack of credibility that regular news orgs have that people feel like they're getting the straight story from Jon Stewart and Stephen Colbert.

2:26: If you're having technical problems like me, check out the rebroadcast at 7pm ET MTV.

2:25: Is he talking? I just hear a voice popping up every once in a while. Time for another force quit!

2:23: Those with visual evidence of the event tell me there was a 10Questions logo up during the time of the video question. That's a little better.

2:20: He said Facebook! He said MySpace! He said Google! He stumbled a bit, but he seems to get it...

2:19: The question is about net neutrality, and Obama says he supports it. That's great! 10Questions wasn't mentioned, however. Boo.

2:17: The 10Questions question! But the moderator didn't mention 10Questions.com! Come on!

2:15: IM from Meeeeeshell about how Obama would engage Iran. He doesn't agree with the saber-rattling. We have to offer them "carrots, as well as sticks." About 84% approve.

2:13: One colleague who was having trouble in IE for Windows said it's working here. No go for me however; still no audio.

2:09: Now the audio is cutting out. I wonder what is going on? The first dialogue with John Edwards was more or less seamless technologically (except for the fact that MySpace's IM client doesn't work on Macs). This time it's painful.

2:05: Why Tuesday's Jacob Soboroff is at the event, so therefore he is liveblogging. Check it out: http://www.whytuesday.org/2007/10/29/liveblogging-barack-obama-at-mtvmyspace-forum/.

One bonus is that he can actually see what is happening. That must be nice.

2:04: Combine the strongly agree and somewhat agree numbers and you get 86%.

2:01: Browser crash #3. They're taking a break and co-host Gideon Yago (or was that Sway Calloway? I wouldn't know) asks the audience to answer the "do you like or not like Obama's positions" question. The strongly agree quotient has gone up to 56%.

1:58: Poll question: "Do you agree or disagree that Barack Obama has the right positions on the issues that matter most to you?" 54% percent strongly agree; 6% strongly disagree.

1:54: Sorry browser crashed AGAIN. I love it when Firefox beachballs and crashes. LOVE IT.

1:52: Ah, I get it, during the answer we are polled for our opinions. When Obama finishes, we get to rate his answer. Better.

1:51: The voting actually seems to be much different this time; it looks like viewers are being polled for their own opinions, and aren't being asked to rate the candidate. Hm. Don't know if I like this.

1:49: Others are reporting no video at all, and some aren't getting audio either.

1:46: One nice addition is the per-question descriptions of the thumbs-up and thumbs-down votes; for the standardized testing question, you can vote on whether his statements would make schools accountable, set standards for students, etc. Nice.

1:44pm: The Flektor Flash player is totally acting up, crashing Firefox, and running my system down. It didn't do this last time. Oh, and there's no video.

1:40pm: So the forum has started, but I can't see the video... not good. What's going on?
