Of course we can all see comments to our own blogs in our admin sections, but how do I see comments about my blog posts that weren’t made directly on my blog post.
If my posts are re-syndicated elsewhere and the item as a comments field, then people can leave a comment about my post and I’ll never know.
Also, I have to be aware if people memedigg or bookmark me, as these posts too have a comments field.

But I think what you are getting at is a comment crawling engine…a search engine that searches the web for comment content.

Wait I’ve missed your point, you want to see where person A has commented in the blogosphere.
Also what about who person A links to (outbound links)…actually PubSub and Blogpulse have this in the profile pages.

So now I see that since CoComments is a social user system, you can probably click on a user and see where they have commented.
I use a tag in del.icio.us to record all my comments.
Same with Webride, click on a user and see where they have commented.
This would only work if we all used the same system.

It’s all over the place, I guess one way it could work is that when you comment on a blog post you enter details like your email or blog homepage…an engine could harvest all this information.
This way the user doesn’t have to do anything more but just comment as they always do.

“Now I did a search for my URL which is great as I can see who has commented on any of my blog posts using Webride, but where’s my ego feed.”

Once again thanks for the icons.
