Link building is perhaps the most important single task to undertake for a websites present and future effectiveness today. This may be in the process of changing slightly with article PR and other strategies gaining ground, but as it stands, Google thinks that the more WORTHY sites linking to you the better, and it will probably remain so into the middle distant future.
The one thing that IS changing right now is the kind of link that is important.
Whereas at one time reciprocal linking could gain you great SERPS, it seems that now more one way links are required (reciprocal links are where another site links to you in exchange for your linking to them, one way links are what they say, just inbound from another site).
