For each publisher it breaks down to one of these methods:
1) submission via their online form. we do this automatically via POST.
2) if their form has a captcha, we queue it for manual submission by a human being (most don't have a captcha though - it's just the big guys)
3)email. the majority of sites encourage submissions via an email address.
4) twitter - worst case scenario is we tweet their account for you
5) publishing partner. similar to (3) email, except the publisher can set their preferred time to receive.
All of the above except (2) is automated. I'd guesstimate that for about 95% of the publishers we support, the submissions are all handled by the software. We want to build it as scalable as possible.
