Personally, when Microsoft announced the discontinuation of old public newsgroups microsoft.public.greatplains and the microsoft.public.dynamics.gp.developer, I didn’t like the idea! I been working the last 3 years on a platform that currently will need to be changed!
Few days ago, I start accessing the community and start replying on the users questions, I really found an amazing difference between this version of community and what I used to work on! I enjoyed working on many new features announced in this post, mainly I touched the social networking during newsgroup questions and saw the blog posts consolidated in one place.
Well done guys!
