I'm quite excited about the 3rd party journal integration; particularly keen on seeing this in SunBlogNuke soon

It occurs to me though, that this still isn't 100% of the story. What would be great is to be able to use ActiveSocial as a 'comments' module for articles, videos, etc. This could be a comment thread against the journal entry for that item.
So you'd add (for example) ActiveSocial to your SunBlogNuke page. ActiveSocial is configured to look for "entryid" in the URL - if it doesn't exist, it doesn't display for the user (so as to allow comments to be linked to each blog entry).
Someone posts a blog, SBN posts to the journal - again, with the entryid.
When someone comments on the journal *or* on the blog entry, it's automatically linked to the journal entry and the blog entry, so it can be displayed on either.
You could also *optionally* configure a setting "Does not support journal" - basically, telling AS that the module can't post to the journal, allowing you to set a content type so that when someone hits the post for the first time, it will get added to the journal; giving you a default fallback for unsupported modules.
The idea being that this gives you a unified comment system throughout the site - all it needs is to understand the tags used by a given module in the query string - while being fully integrated with the social paradigm.
Would love to also see this implemented with "thumbs up / thumbs down" ratings (ala anti-spam), both for the post and for the comment itself. Then you could implement "most popular posts" and "most popular comments", etc.
I think this idea would make for a more seamless social experience. Sorry if this is a bit convoluted - happy to explain the idea more if needed.
