Should I request reinclusion or not?

[Seattle_SEM]

Our site launched in September, 2009. Since that time we have struggled to get any significant portion of our content indexed.

We are getting traffic though, maybe 60-100 visitors per day from Google natural search. But if all of our content were indexed and ranked, I think this should be closer to 300-500 visitors per day.

Is six months unheard of to build something from scratch and make it an SEO winner?
Should I just keep working on the site and getting links?
Or should I do a reinclusion request, and see if that works?

The site itself is fine. Good links, good content, reasonable crawling. I'm at a loss.

Thanks in advance.

I'd just keep working on the site.

If you did file a reconsideration request, what would you say? Is there something wrong with the site?

We had some internal content duplication issues when we first launched, but I those have been cleared up now.

I think those kind of issues clear up on their own - without a reconsideration request.
