I can only assume that this is a joke.

Several of the people on the list don't really have anything to do with programming at all.

There are some high-profile academics certainly worthy of recognition who aren't there.

There are some who have created programming languages and libraries that are high profile today, but some of them are very much more popular than others.

There are some bloggers, whose influence reflects their self-promotional abilities more than any real contribution. People might read them, but I'm not sure how many people are influenced by them!

Ultimately, the list is very focussed on people who are visible in specific parts of the industry today, but ignores many of the pioneers whose work reverberates throughout the industry to this day.
