One year ago or so one of my posts ended up within the first few items of the home page and my blog got about 35K views over 2 days. The blog is hosted on a commercial platform and had no server issues.

10 years ago a post from @Bluehat for something we were working on* made #1 and generated about 7k clicks in 2 days.
Would suspect that number is much, much higher now.
* The Hacker Fair reverse job fair at the Hacker Dojo. #2 was "the CIA got hacked". Proud of that one.
