I always thought that a wp.com post sent an automatic ping so that RSS readers would pick it up. My latest post from nearly a day ago has not been picked up on RSS readers, and it didn't show up as an automatic tweet on Twitter as it usually does either.
What can I do to ping a post that's already been posted? I've tried going in and editing it just so I could save it again to see if that works, but nothing so far.
The blog I need help with is lettershometoyou.wordpress.com.
