Found this a while ago and I now have multiple accounts and use it for all my blogs
you know when you have a big ping list in wordpress and you go to post and it hangs there forever? that is because the ping services are hanging up the posting, wordpress is trying to ping all the services at the same time it posts
I use this autopinger now...it scans your blog every 30 minutes for new posts and then pings all the services when it sees a new post
it is free
