After investors learned that subscriber growth didn't hit targets for the quarter, Netflix stock plunged losing about 20% of its value.

Since the announcement of HBO Go allowing users to subscribe to a cable-less subscription this news is not surprising. Netflix also said they made a mistake by increasing subscription prices by a dollar which was the reason its stock tanked.

This is just our current market culture. Bubble, bust, bubble, bust. No one cares about the long term anymore.

Is anyone thinking of buying netflix stock low? Are there any predictions concerning future value?

I'm not aware of any professional predictions concerning the future of NFLX, but my personal opinion is that it will continue to sink for some time. They have a number of factors going against them. More competition is coming from other online streaming services, and I think more importantly, they're locked in a battle against ISPs that are throttling their content and requiring netflix to pay for their own infrastructure. Unless the FCC rules in favor of reclassifying ISPs as common carriers, netflix (and all online streaming services, really) are going to face an uphill battle in being able to provide content to their audiences. Additionally, I think netflix has a number of flaws that are slowly pushing people away, namely that the streaming offerings tend to be several years old and that content is often removed from streaming without any notice to consumers.
