Pulse of Open Source is a new site that aggregates the Twitter messages of thought leaders and participants in the Open Source Software community. It's a great example of the value that can be added on top of a simple aggregation of dynamic niche content. It's also a good example of how you can find value in Twitter without even having an account of your own.

Inspired by the site Pulse of PDX, an aggregation of Twitter messages from users in the tech-rich town of Portland, Oregon (where I live) - these Pulse sites provide a model that could be used to create a central location for live discussions on any topic.
