I would like to know why this question Sniffing for iPhones was closed and this other question How many GPS channels make sense? my flag was declined.
The two question is really good question, I really want to know the answer, but not here in EE.SE. In my understanding the two questions are off-topic, the questions are asking about some doubt in use of a communication protocol.
I flagged wrong?
I agree 100% with Stacey's analysis, but when you say "I flagged wrong?" the best thing to do is just flag how you see fit at the time. As long as you're doing your best to try and improve the site at the time for a lot of things like that there's not really a wrong / right decision.
Even when you get direct close / re-open votes I've seen questions closed I think should have been left open and others I think should have been closed that are left open. Everyone will have a different opinion and that's the idea of everone apart from moderators needing five votes to close or re-open a question.
The closed statement on the iphone question puts it well:
"Questions on the use of electronic devices are off-topic as this site is intended specifically for questions on electronics design."
The reason why the GPS question is ok is because it is related to design. The question is essentially, "why is x designed this way?". The iphone one is not a design question.
The GPS question: say you want to build a GPS receiver. That's electronic design. The number of channels is one of the first questions you've got to ask yourself. This will determine which receiver module you will use in your electronic design.
