Great article (read the full story at http://mashable.com/2009/08/01/facebook-vs-twitter/# or “via” link above) on when we use these two social media tools.
This is more about a reflection of how people use these tools and not necessarily how they should use them. I think we all are still trying to figure out best practices in the social media realm. Soren Gordhammer is accurate in that we all seems to reach out to Facebook people we already know and they tend to be more local.

I would add that that Facebook has a mature MySpace persona, and Twitter has emerged as more of a business tool for the masses.

Linked-In which is not mentioned, may have reached its peak. It has transcended all professional fields across the globe and it will be here for the long-haul… but it may slow in its growth.

Look for other “local” social outlets to be born as we move forward.
