I think it is quite widely used by bloggers to notify google and other search

automatically accept all pings, then you open yourself up to spam. The pings need to be
filtered.

Anyway, here is the spec

http://www.hixie.ch/specs/pingback/pingback

So having read it again I think it has a lot of good things:

- the X-Pingback header is a good for photos, that cannot contain links - the link relation in the html

I think the only thing I am really against is the use of the xml/rpc.

Perhaps I can convince the semantic ping back people to enhance the ping back service to
enable application/x-www-form-urlencoded results.

I think that with that, and allowing that the ping back service be foaf+ssl enabled, one could get something interesting.

Yes, the clever thing about this restful ping mechanism is that - apart from
being so simple that it feels like some people may die of a heart attack hearing of it
- is that we can know the identity of the pinger, by placing the form behind a
foaf+ssl access control layer. I don't think this completely deals with SPAM - you can't deal
with SPAM if you want to be open to novel interactions, but it does

Ok, I'll rewrite my suggestion to the pingback people and the linkeddata list.
