Have you ever gotten directions from someone with descriptions of one mile, two left turns, three stoplights, but no street address? And the ending address is what you really need to plug into your map application or GPS. The rules about giving directions have changed.
In business, you can adapt to the new rules like Verizon is doing with its rollout of 500 downloadable applications for their phones, (although new iPhone apps like copy & paste or a radio player came loaded on Verizon's Palm Centro last year). You'll also see the new rules about using your database to create most-popular and recommended lists, as well as offering text updates.
The other option of course is to ignore the rules, as in the company formerly known as GM (of which you are now part-owner) and the major newspapers.
