What would be 'virtual' about it? - Andy Roberts

Virtual in that the blog would not have its own unique domain name. It would exist only within a FriendFeed room. - Phil Glockner

No because once you have allowed people to join the room (and thus see your posts) you have given them the right to post anything they want - MikeonTV

Also all blogs are virtual. A non virtual blog is called church - MikeonTV

Of course it would be possible. In fact, once Google Reader offered the functionality of adding notes to shared items, that is essentially what they did -- make possible a virtual blog. The stumbling block in such instances is that the original creator doesn't have as much control over the generated content and subsequent conversation that is enabled on a standard blogging platform. - Jill O'Neill

@Jill it does look like once you grant users permission to comment on a message you enable them to create their own. So you have a MetaFilter. - MikeonTV

We are already doing it with Rooms! Forget RSS give us XML. - Igor The Troll יִצְחָק

No unique domain name- so a bit like Blogger then. Lets see, we've got reverse chronological order entries, and we've got comments. That's sort of blog-like then, I'd say. With members it becomes more like a multi-author blog. - Andy Roberts

Micro Blogging community! Like an Opera House where everybody sings! Or a True Senate! - Igor The Troll יִצְחָק

You'd have to be OK with having no Google Analytics, no SEO, etc. - Rubin Sfadj

Ha, analytic? SEO? Next you will want to Drop your Adsense JS! LOL Try Branding not giving yourself away for nickels and dimes. - Igor The Troll יִצְחָק

I think you could run a primitive blog from a room, definitely. It wouldn't get trackbacks, formatting or any of that cool stuff. But it could be a nice basic publishing system for your FriendFeed followers. This links to an effort I did on that yesterday (http://tinyurl.com/44k5k3). Created a blog entry where the initial direct post is the blog post title, and the subsequent comments were the content of the blog post.Then people added their own comments. - Hutch Carpenter

You could definitely do that, it just depends on how specific your definition of a blog is. Like everyone said, there would be no trackbacks, analytics or SEO and you wouldn't be able to change the theme of your blog. - Ethan Klapper

Thanks everyone for your great input. The "anyone could post in a room once invited" would be a show stopper, I guess. But it would be interesting if a blog-star appeared purely from within the context of FriendFeed. - Phil Glockner

Yes, absolutely. - Mike Reynolds
