I would like some guidance on how to pick the correct Stack Exchange site to post a question to. This problem has come up in the past, and I have seen that questions inappropriate to the network get downvoted or deleted.
I expect other newbies have the same question, or even that this question has been asked before, but if not please help.
For example, if I asked, "How reliable are cheap electronics, like laptop chargers, that are sold on Amazon or new from Ebay, and is there reason to buy name brand instead?" Would this question belong on Electrical Engineering, otherwise how would I identify the correct network?
