Blogging does need a search engine, as Colin Devroe and Brent Simmons have said, but Devroe raises an interesting point as to deciding what’s a blog these days; many publications are structured and formatted more or less like blogs. What we need is an independent or hobbyist blog search engine: personally, I don’t need a blog search site that includes The Verge or io9. Maybe the folks behind Wiby could take a separate stab at blog search?
