* I have limited character allocation to wax poetic, and my listing is for a company (Pivotal) with 19 established offices and more that aren't really publicised yet.
* The requirement for positions in given locations changes constantly. One month I went through our list and posted those locations. By the end of the month, it was out-of-date.
* Then there's the problem that I'm listing for multiple disciplines. Adding an ad for every single role seems like it would be detrimental.
* Last but not least: I can earn a referral bonus from the ads I post. I'm not sure how my ad being slurped into a different site helps me, given that I expect my link might not be very prominent. (edit: except you seem to reserve a spot for URLs, so let's drop this one and chalk it up to "Jacques speaks before he reads, episode 20 kajillion")
Still, I'd be interested in making it work better.
