As far as attracting mainstream advertising for the site goes, my guess would be that the numbers simply aren't there any more when it comes to the VX, and likely never will be again on a long term basis.

It's site traffic FIRST that attracts advertisers, and if the advertising isn't going to be seen by enough traffic, it simply makes no sense from a business standpoint to invest.

Sure, there have been suggestions here and there over the last few years that the VX may turn into a "future collectible", but even then that possibility is partly based on the few remaining of the low production numbers to begin with. So even if it DOES happen, the low remaining numbers of VX's would ensure that such a resurgence in popularity would only be a short term and sporadic even if values happened to occasionally skyrocket as they sometimes do.
