This trackback URL can be used as a pinging service for the blog in general…usually the problem is if I’m posting something and want to pingback 3spots, but what I’m posting about doesn’t refer to a particular 3spots post, how do I let them know just the same (I want a generic PO Box for the blog).
Well I can just use the trackback from the “about” page as a general trackback for the whole blog in general…I explained this in an earlier post.
If I were at the blog I could leave a comment in the “about” page, but if I’m posting on my blog and want to let several people know about my post, I can just trackback their “about” page.
Over time the about page would accumulate heaps of trackbacks all related to different topics.
To take it further, on your “about” page you could promote links to several blank posts, each of these posts can be set up with a topic name in the title (it wouldn’t be totally blank, maybe the body would read…”This is a place where you can ping me about things to do with folksonomies/tagging/social bookmarks.”)
If a blogger wants to ping you (trackback you), but can’t find a specific post on your blog to trackback, then they can just use the general trackback post (the “about” page), but first they could consult your topic trackback posts.
eg. If I was posting about the topic “folksonomy” and wanted 3spots to know about it I could trackback the 3spots “folksonomy” blank post…if 3spots didn’t have a topic trackback post, then I would resort to pinging the “about” page.
Another thing, what if I’m writing a comment in someone’s blog, how to I ping others about this…eg. if I wrote a comment in blog A, and I wanted blog B to know about this comment how do I do this.
Problem is a comments box doesn’t have a trackback field…the best thing I could do is at the end of the comment, list the actual URL (not the trackback URL) of the “about” page of blog B.
But then blog B won’t see this in her ego feed, as the comments field isn’t really indexed by blog engines.
