Recently I searched LinkedIn for a group for people who, like me, are interested in how global software development (GSD) teams can work together more effectively. When I didn't find one, I started one. Please consider joining the Global Software Development (GSD) group on LinkedIn if this topic interests you too!
I have yet to find a good aggregator or portal that collects relevant blog posts, topics, etc. on GSD, either. If you know of one (or more), please post it in the LinkedIn group or send me a message via email or twitter. Thanks! (Eventually, if none turns up, maybe we'll build one ... 'better to light a candle than to curse the darkness')
