I've never really observed that. Actually, my impression has always been that there's a profusion of firehose-style group blogs like Huffington Post or the Daily Kos (with LessWrong being an unusually successful version of these), but that slow, thoughtful, non-instant-response, essay-format content like More Right's present lineup can be hard to find. The only thing I'd suggest regarding content volume is that regular, frequent updates would be helpful.
Various people (including Konkvistador who has been talking about it the most) have launched their blog More Right
"A group blog, More Right is a place to discuss the many things that are touched by politics that we prefer wouldn’t be, as well as right wing ideas in general. It grew out of the correspondences among like minded people in late 2012, who first began their journey studying the findings of modern cognitive science on the failings of human reasoning and ended it reading serious 19th century gentlemen denouncing democracy. Surveying modernity, we found cracks in its façade. Findings and seemingly correct ideas, carefully bolted down and hidden, met with disapproving stares and inarticulate denunciation when unearthed. This only whetted our appetites. Proceeding from the surface to the foundations, we found them lacking. This is reflected in the spirit of the site."
