Looking for some suggestions for useful discussion groups, articles, success stories, reference apps, and tooling (.Net) on the subject of event sourcing.
I am already familiar with:
Fowler's article: http://martinfowler.com/eaaDev/EventSourcing.html
Greg Young's Article (with downloaded docs in the comments): http://codebetter.com/gregyoung/2010/02/20/why-use-event-sourcing/
Greg Young's excellent (draft) article on DDDD: http://abdullin.com/storage/uploads/2010/04/2010-04-16_DDDD_Drafts_by_Greg_Young.pdf
Anything else I should be reading and looking at?
You should look at this implementation of an EventStore as well as these two implementations of mini-systems based on CQRS with event sourcing.
EDIT (2011-05-18): NES (.Net Event Sourcing) is yet another implementation available to reference.
It may also be worth following the Google and Yahoo groups related to CQRS & Distributed DDD.
