Every time I check our report card we are around 200 visits a day. With 500 being the needs work low score. At 40 days old we seem to be doing well at the other indicators.
There is no doubt in my mind that Space Exploration asks and answers questions critical to the future of humanity. From this it follows that the site will pass Beta, and become a resource for the foreseeable future.
If we continue to ask and answer good questions, is that enough and time will bring more visitors, or is there something we as a community are not addressing?
