Operation Meet Bono failed, but it was still a great day.
I got there around 2, got my ticket 45 minutes later when they started handing them out, and then I scouted out the building until I came across a small handful of U2 fans waiting by a side entrance. I waited there, chit chatting with some of them, from 3 until about 4:40 when I had to go in for the taping, and nothing. I don't know what time he ended up entering or if he ended up using that side door. There were only 16 people (including three or more ebay-ers) there on the sidewalk, so I hope everyone there was able to meet him.
But Bono was great and he was absolutely gorgeous. I was sitting in the section that's kind of off to the side of Stewart's desk, but it was the closest to where Bono walked on stage. When he walked off stage after the interview, I pointed at him, waved, and made my U2 shirt pretty visible and I got a smile, a point and a wave back! It might not have been directed at me, but I feel like it was so lets go with that

About Jon Stewart, he did a Q&A segment before the taping. I asked him how the show was able to get Bono as a guest after years of trying. He jokingly responded that he didn't even know that the show was trying to book Bono and then talked about the lady who does the booking. And when Jon said "we've been trying to get him on the show for years now" in the monologue, he was talking about/mocking my question a few minutes earlier and thats why the whole crowd laughed and Stewart stopped talking

And after the taping, Stewart pointed me out again and asked if the shirt I was wearing was a U2 shirt, and then he asked if I enjoyed him being on the show. So I got to talk to Jon Stewart more than anyone!
Also, Bono talked for about 30 seconds about the wonders George W. Bush did in Africa, and that was unfortunately edited out of the interview.
I didn't get to meet him, but it was a great day nonetheless
