I have been using several websites to ping my new posts, I recently discovered ipings. It seems easier to use than pingomatic which I have found recently to be slow loading and not really that user friendly. There is one problem: you can’t ping again for two hours! I understand why, but you if you are too busy posting several times, it’s perhaps too long to wait. I’ve been posting several times a day recently, and so I think the limitation is a bit strict. Still. Worth trying.
