Google has just announced a new blog ping service joining an already very crowded space – I’ve been using Pingoat.

Today we’re launching the Google Blog Search Pinging Service, which is a way for individual bloggers and blog platform providers to inform us of content changes. Blogging providers who syndicate RSS/Atom/XML and want to be included in our Blog Search index can now ping us directly. We’ll continue to monitor other pinging services and will contribute change notifications to the community.
