Dangers of Social Network Analysis

Just reading a whole bunch of posts about the dangers of social network analysis and came across this one from the daily Kos. This is a follow up to a post I made about how the NSA is using social network analysis to detect terrorists but how this becomes an invasion of privacy since they have a huge database of phone call records. There is also a poll from the daily Kos blog:

Social Network Analysis is:
a threat to democracy and civil rights
possibly a threat
kinda boring
not a threat to democracy
safe in the hands of an upstanding leader like george w. bush

So far, 66% feel that social network analysis is a threat to democracy and civil rights. Interesting thing to note is that I've got all these posts from subscribing to the SOCNET mailing list. One funny thing is that if you rearrange the letters in NSA, it becomes SNA.
