Bob Pearson, of Dell, recently presented insight into Dell's learning relative to the web - and in my opinion, they are spot-on with their findings. I've taken the liberty of condensing the learning below.

What Dell's Learned so far?

1. The online world is undergoing the most significant transformation so far. 
2. The # of conversations is exploding. 
3. Customers want to speak with us in their first language. 
4. New countries are formed every day that are not being treated with the full respect that their nation's population deserves. 
5. Watch out for content pushers. 
6. You new home page is really cool .... but do you know where it is? Today's home page is a Google search Results page.  The Traffic that matters is not about you!
7. If you build it they will not necessarily come!
8. Less than 1% of a personal time online will be spent online purchasing.

What has Dell's Key Learnings & Action been with all of this?

1. The most important thing you can do is help customers w/ their technology problems.
2. Blogging is global ... blogging is multi-lingual ... blogging is by community of passion ... blogging is not "one blog". 
3. Would you rather do a focuses group with 10 people or listen to 100,00 people debate ideas for a few months and ask them questions throughout the process? 
4. Customers are partners and partners join together to make a difference. 
5. Communities are more powerful than individuals, Communities want to help each other improve.
6. The online experience at work should be similar to the online experience at home. 
7. Join your customer's communities and become part of the solution.
8. You can be easy to see, and should be easy to converse to.
9. If you are dealing with an issue be truthful, transparent and diligent in updating your customers.
10. Your customers are people not lines of business.  One customer or Employee --> Many communities.
11. Measurement requires thinking outside the box.  Don't try to fit old thinking to the new environment.
