I understand that WP 2.0- pinged the services the moment a new post is published, regardless of its timestamp (so, even if the post was scheduled to appear in 1 week, the services were still pinged immediately upon hitting the Publish button).
1. Has anything changed with this regard in WP 2.1?
2. If not, is there any reliable plugin for managing pinging (beyond Skippy’s WP-Cron, which admittedly is not very reliable)?
3. Are the services pinged also when the post is saved only as a Draft (I assume, not)?
The new cron system should ensure that posts don’t cause pings to get sent until they actually appear on the page. I think. I have not examined that piece in great detail, but given what I have seen, it makes sense.
