(This remark is probably more appropriate as a comment to your question than an answer, but alas there is insufficient space in the comment field for the remark, thus my choice to post it as an answer instead.)
I see 3 up-votes for your question at the moment, so I guess at least 4 people here do indeed want to see more questions for this community, but my personal experience is that many members of this community are rather hostile to most questions outside a very narrow scope (no training questions, no certification or exam questions, no academic questions, no SOHO networking questions, et. al.).
It goes without saying that there are vastly more amateurs in Network Engineering than professionals, so if people here really want to avoid automatic closure, then opening up to amateur-type questions might be a good idea.
I'm a professional of many fields, but not a professional Network Engineer, so I'm unable to post either questions or answers within that narrow scope. That said, however, I've nonetheless invested quite a lot of time composing thoughtful, intriguing questions on the main site so as to try and contribute to this nascent community, and my amateur contributions have thus far clearly been unwelcome.
For example, I posted one question on SOHO networking which only one hour later was well on its way to being closed when I deleted it voluntarily. The first vote to close the question was rendered only 6 minutes (less time than I had spent proofreading it before posting) after I posted it. When I voluntarily deleted the question before it was closed by others, I involuntarily uttered a surprised and sardonic chuckle to discover that doing so had earned me a "Peer Pressure" badge... as if caving in to peer pressure was a praise-worthy character trait: one of the very few negative aspects of the SE community model I've encountered thus far. I posted another question on academic preparation for working in this profession and it too was closed <24 hours after being posted.
So although I hope I'm mistaken in this regard, I suspect that as long as those sentiments remain a popular force here, the questions-per-day ratio for this community will continue to fall. When I first looked at that ratio on day 1 of the private beta, it was very high, around 22 questions-per-day. I looked again towards the end of the private beta too, and IIRC, it was down to around 15 at the time. At the moment, it's down to 11.4 questions-per-day (about halfway between the 15 and 5 threshold numbers describing the health of a SE community).
I saw a similiar trend with a slightly older community (Reverse Engineering whose question-per-day ratio, after 60 days in beta, is currently below 1), So although it's clearly too early to predict for Network Engineering, based on those three data points alone, I worry that this community may have a rather limited lifetime regardless of encouragement such as yours.
