Webrings, pic posts, banner exchanges, traffic pyramids and CJs?

There was a time when everyone (and i do mean everyone) seemed to be talking about them on sponsors and resource boards these days, it seems all we hear about are TGPs, Link Lists and Traffic Brokers.

Have these sources of traffic really died their death or are there still some good sources of traffic to be had from those types of sites?

Your thoughts?
