I don't think we're going to be shut down just comparing our numbers to a few others that have been in beta almost twice as long:
All 4 of these sites have been in beta for almost twice as long as this site and their numbers aren't too much better than ours are now. It takes time for these sites to build up.
On another note, I have not heard anything concerning being shut down, regardless. Our numbers are low, but that is because of the community. If we want this site to succeed, we have to promote it.
Ask good questions, jump on top of recent releases to increase traffic (this summer will be a huge opportunity with all the big releases), and share share share (yes I mentioned this).
You see a good question, use the Facebook/Twitter/G+ links on the side to share the questions with your friends. If you see a question you would really like answered, whether you asked it or not, offer a bounty of rep for it.
If you have ideas on how to promote our site on a large scale, don't be afraid to post them on meta. As far as I know the SE team checks in on this site occasionally on the meta for posts like that. From what I hear, sites that have very active and enthusiastic communities have the chance to get funding for contests and events; Skyrim Vs MW3 for example.
This site depends on the community to succeed, which can be a great thing, but can also be a downfall if the community just comes and goes. So if you have a few favourited questions, tweet them, post them on FB/G+ (redundancy!) and chances are you'll get a few people to check them out too and possibly involved in this community (Also a nice way to nab some badges on the main site).
I feel with our Anniversary here, It would be appropriate to update this answer with our stats after 1 year:
SNIFF I'M SO PROUD OF ALL OF YOU :D
