Sort of, but first measure the aspects. If domain.com is a flat site (one set of content, no major updates) with a huge amount of respectable back-links and you register domain.org with a flat-site too, no major updates, probably promoting a game download affiliate site, less back-links or none because your domain.org copycat isn’t popular than original domain.com so you have to actually work for those back-links, if your content slightly surpasses the length and quality of domain.com it still would not beat domaim.com because of the huge back-links domain.com has. It also depends on keyword optimization (what term do you want traffic from?) if the term is simply domain as in of domain.com and your site domain.org and you optimize it better it still would not do better because of the back-link aspect but probably (I emphasize) would be on the first search result page simply because of the one main keyword in the domain name.

If you have a domain.org mimicking domain.com with the same rules applying for domain.com as above, but you have a forum with some auto-posted content and some quality responses, and you actually work a-bit on getting high quality back-links, it has the possibility (I emphasize) because of the content aspect alone. If you match domain.com optimization exactly as your mimicking site, with no quality back-links compared to domain.com, then you won’t outrank domain.com. Keep in mind we are talking about keyword domain as in domain.com and domain.org.

It seems you would be interested in this by keeping it and monetizing this rather than selling it, if so you shouldn’t just expect to forward the traffic to domain.com for any reason, you should follow general monetization dos and don’t, mines is build a user-base before you try to profit from your site(s). Auto-generated content alone can give you a good PR, [see the results from experiments on this forum] and when you seek back-links from high pr sites and blogs (?) that increases PR, when you post quality responses to those auto-posted content that lands you on the quality content field (supposedly). Domaininfo.com against domain.com will never beat domain.org against domain.com. Hope that helps clarifying some stuff, or did it?
