The only people who said blogs were dead were the corporate overlords who bought them all up, tried to lower costs by cutting staff, and realized 18 ads on every page turned readers away.
Trust me, I know. I worked at AOL from 2006-2011 or so. I was around the whole “let’s just make a bunch of sites, throw ads on them, and link to them from the AOL homepage” and holy shit, it worked until it didn’t, I guess.
