Kinda like a site where you can go to intermingle with other members who like and use Microsoft services products and the like? Could partly say this site (Windows Central and it's forums) serves some or most of that purpose which you stated. Unofficially of course...
Yea, but I am talking about on an official and in a face to face way, actually interacting and working together during the development of ideas and features instead of an after thought after they already invested time and energy into something that they eventually change direction from because lack of communication.
Most things in life get refined, its not all that different from the way things were designed and built pre-ww2, back then it took a car manufacturer more than a couple of years to go from design to finished product, because each phase had a different group of people in a different location. Design team drew up plans and sent those to the engineers, who would look them over and tell them what would and wouldn't be possible then send the plans back, this happened a few times until they had a working design, then they sent that to the accounting department and they looked it over and said what would or wouldn't be cost effective then sent the plans back to the design team to fix and then it would start all over again, then to the production team to make a prototype and they would find flaws that everyone else missed and all over again.
So back then there was a forward thinking individual who had the idea "Hey why don't we get all these people in the same room and have them work together to save time, but the big wigs in the good ol' boys club told him they know what they are doing and scoffed at him. Anyways at the end of WW2 when the U.S.A. agreed to help Japan get back on their feet economically they got the great idea to sent this half wit with his new ideas over to Japan and let him use his ideas to help them. By the 70's Japan had surpassed the U.S.A. in technology because of the organized way they planned and built products. What took a US Car manufacturer 4 years only took Japanese Manufacturers 6 months.
Planning and being organized goes a lot farther than people think. Nowadays when markets are so volatile and consumers are so distracted by little things it seems more important than ever to stay connected with your consumer group.
