Blogospheric navel-gazing is always a pleasant diversion; today, Dan Drezner looks at the dispute over whether or not “portals” are the way to go for budding bloggers. Dan correctly points out that only a few bloggers can sustain the level of traffic needed to make the “portal” approach worthwhile—and this applies as much to the “techbloggers” as it does to the “warbloggers” that the Ecosystem statistics are biased towards.

I, like Dan, think Will Baude’s comment is worth repeating:

Tyler Cowen thinks that there are so many good blogs out there nowadays that the most widely-read blogs will be those that “cream-skim” (that is, taking the most useful posts from a wide variety of blogs).

Pardon, but an RSS feed can do that. The reason I don’tread Instapundit is that I don’t particularly agree with Glenn Reynolds about what’s wheat and what’s chaff. Look at my blogroll, which contains a number of fairly low-circulation blogs, and you could probably guess that.

I think the value of “portal blogs” will be somewhat reduced when people figure out how to do category-based aggregation (or topic-based aggregation) of RSS feeds—ironically, bringing weblogs closer to the early 1980s topic-based discussion format pioneered on Usenet before much of its value was destroyed by trolls, crapflooding, and spam. Where the portal blogs like Instapundit will still win, however, is in the area of editorial control—separating the wheat from the chaff, to borrow Will’s phrase—by not only saying “this post is on a topic you may be interested in” but also “this post is a good post on that topic.” To some extent you can add some of that control by filtering the aggregated RSS material against a trusted OPML list, but it’s still not quite the same thing as having a human editor.

In the end category-based aggregation (CBA) will not only help end-users, it will also make it easier for portal editors to pick and choose from a wider variety of blogs. I don’t know how many blogs Glenn Reynolds reads a day, and I suspect he gets most of his links to less-well-known blogs from reader submissions. A mere mortal can only read so many blogs, even with an RSS reader. CBA should make it easier for the portal editor (and for everyone else) to scour more of the breadth of the blogosphere for good material, which should be a win for everyone involved—more eyeballs for budding bloggers and higher quality material for the portals.
