We started using Google+ Hangouts at our Queen City DotNetNuke User Group this past year to stream our meetings and share them with anyone in the greater DotNetNuke community who may be interested in watching from afar. Last week the ODUG streamed one of their meetings using WebEx. I'm just wandering what streaming services you may have used and what you thought about them... advantages/disadvantages, gotchas, etc.
What streaming service do you like most and why?
