Over 80 percent of blog posts are probably spam

Doug Caverly highlights a Matt Mullenweg quote indicating that about 1/4 of all the blogs ever on were spam (aka splogs). Now, that’s probably a higher fraction than for the blogoverse overall, because:

But there’s one more factor. Splogs have much higher posting frequency than real ones. 10-20+ posts per day is not uncommon, and 50-100+ is not unheard of. That’s 5-10X the post frequency of even the more active human-written blogs. So let’s assume:
