In the case of mint.com I think it is appropriate not because we need to understand the network layers, but so we can make sense of the privacy impact of the tools.
We need to be able to choose which tools to use, and for folks on the Internet in general it can be good to know.
That said, that particular question could be refined to described WHY they want to know, otherwise it might not belong.
As for the Quicken troubleshooting, the best place for that is probably Intuit's help desk. However for better or for worse, it is a pretty common program in personal finance, and somebody here might know. I looked over that question quite a bit and I still remain torn. The part of me that wants to troubleshoot computers vs the site. But ultimately I think the question is too far out as a troubleshoot, and therefore too localized.
I think mint should stay and quicken should be closed.
