Ecosystems -- for this and that

I just came across Eclipse Ecosystem (a blog by Donald Smith, Director of Ecosystem Development for the Eclipse Foundation).

This is a blog with a difference, as exemplified by the post: Measuring the Health of Ecosystems

It made me wonder what some other communities of interest would look like when put under a similar magnifying glass -- if you could do it.

• Lotus Notes/Domino Ecosystem?
• Linux Ecosystem?
• Microsoft .NET Ecosystem?
• IBM Mainframe Ecosystem?
• IBM System i Ecosystem?
• NetBeans Ecosystem?
• Firefox Ecosystem?
• Blogging Ecosystem?
• Skype Ecosystem?
• (and so on)

I wonder what they would look like. ... Is anyone out there in the blogosphere able and willing, or daring enough, to set up any other ecosystem blogs?
