The New Communications Forum put on by the Society for New Communications Research is a great event because the participants are some of the leaders in social media around the world. Many of the participants know one another very well because they communicate through social media on a daily basis, that's one reason why the level of conversation and good fellowship is excellent. This is not your social media 101 event. You should just attend New Comm. Forum just for the evening dinners, but in addition they have great panel and speaker events during the day.
I regret I will not be able to make the event this year, especially as I am a Research Fellow with the Society, I am speaking in New York at the PRSA's Digital Impact conference later in the week, but if you are attending for the first time, and would like to check out this great event, let me know, I have some discounted tickets available.
