In the context of How to leverage reputation systems of other communities to encourage participation in your ownHow to leverage reputation systems of other communities to encourage participation in your own, related to this meta question: Should this site cater to those trying to build community platforms?
The question listed above I closed a few days ago as off topic because of the technology element. We have always discouraged technology based questions. I will admit that this question does seem a bit different than all of the other questions closed for technology reasons, but I still am not sure how this isn't primarily technology based? Am I taking the verdict of "no technology" the wrong way? At the end of the day, it's asking for a platform to link two communities.
Even if we did deem this on topic, should we allow these "shopping questions?" Other SE sites have mixed opinions views on them; it works well for some and not well for others. When will a shopping question be too technology based?
