I'd love to see some more advanced options for pinging services when posting. Particularly I'd like to not have to wait for all the pings to complete when posting, its hung on quite a few occasions. Perhaps the option to ping from a cron job or admin option. I'd also like the ability to set up custom update service pings based on the category I am posting to. If I'm posting about my dog then I don't necessarily want to ping a tech update service, despite the fact I mostly post on tech related issues.
