@dario - When you load a bunch of links, you don't want them all pinged or you'll put yourself in the sandbox. (Imagine google finding a few thousand links all at once!) By default those links are split into RSS feeds and those RSS feeds are dripped out on a schedule. I believe the defaults are files of 20 links put out twice a day (so 40 links/day). In that case if you added 2000 links, it would take 50 days for your links to be fed out. If you want it put out faster, just tweak the feed size and scheduled release rates. We don't invent new feeds but instead build feeds with the links you submit.
