Deborah: This is funny ... I just writing a post about NpTech Mashups and came here to point to your article re: socialsource and discovered this! I agree with mashups, but it includes the whole concept of social search as well, I think. But when does the information stream get so unyielding to cause all to scream with information overload sickness? I think we need a mashup of automated mashups of data streams and some human editing.
