Host Chris Hardwick did particularly well in my opinion, he was funny, charming and actually seemed to know and respect the internet crowd (unlike some of the other Hollywoodites, who were clearly forced to be there and didn't know even who they were giving their awards too)
This first link is to the full awards show:
And the second to the Sourcefed recap:
I do think it's important to point out that these aren't the 'Youtube Awards'. The big three 'tubers, Smosh, NigaHiga and RayWJohnson only received three nominations between them and their associate channels and it was actually Yahoo's 'Burning Love' staring Ken Marino, which won awards for Best Male Performance: Comedy, Best Ensemble Cast, Best Guest Appearance, Best Comedy Series. However, it was awesome to see so many familiar faces together.
Possibly to keep the awards show short and sweet (the final cut is only about 2 hours long exluding adverts) quite a few Streamys winners were announced pre-awards show. The winners were given a round of appalause and got to stand up and show off their trophies but I believe this undervalued some of the awards. For example, MachinimaPrime's Halo 4: Forward Unto Dawn did really well, receiving 4 wins over all but did not seem to be so successful on the night.
As with all awards shows, on the night there were a few surprise winners and losers. Such as Toby Turner, a.k.a Tobuscus, losing out to Kaseem G of California On and RedvsBlue missing out to Tom Hank's Electric City (unfortunately and unsurprisingly the man couldn't be there to accept his award) . Plus the legendary Larry King not winning a single Streamy despite being nominated twice. And of course there were the occasional hiccoughs you expect from it being broadcast live, such as the incredibly unenthusiastic Jackson Rathbone and Jamie Kennedy not realising they had to read out the nominees. And a slightly odd and off key rendition of Shontelle's 'Impossible'. But over all it went as smoothly as a stream (y).
In conclusion I think the Streamy's were very successful and as the internet becomes more and more relevant in the modern age I believe they will get better and better.
