Thanks Luis! I am in total agreement that Lists are critical. You will see that even more so in part 1 of this publication. I looked into and signed up for Qweboo based on your like of my tweet to understand more about what you offer on this front. If I understand correctly, your product is in open beta and will be designed to supplement Lists by organizing users’ tweets by the topics they talk about. If you can get that right, it can be a critical piece of the puzzle. In fact, Twitter should be looking at whether they should buy you to integrate your algorithm into a solution that compliments Lists. You may want to discuss with @jess on Twitter when you are ready.
