This isn't unique to the Aviation SE, there are questions of this type on nearly all of the different StackExchange sites. Generally, I would prefer that we leave it up to the discretion of the OP to decide which answer best answered his question.
There are many questions which receive multiple correct answers. StackExchange, especially the Aviation SE, often has questions with multiple answers that are each phrased differently, but they are all correct, and only one can hold that coveted green check mark. It's a slippery slope to deny questions simply because there are multiple correct answers - we just have to ensure they're not opinion based. Asking "Are there airports connected by taxiways?" is different than "Are airports connected by taxiways cool?".
People can answer at their own peril (peril being the chance their answer is not selected). Poor answers will drift to the bottom, and quality answers will still float to the top.
I could potentially see the issue with the wording if it were "What are some airports connected via taxiways", as that's a bit more of the Quora domain, but the "Are there any.." fits pretty nicely here.
