None. People who have time to cultivate a following are very rarely the people who deserve one.
In the long run it is the content that matters, not the content creator.
If I did follow anyone it would be a set of obscure computer scientists like Tony Hoare (mostly retired), Christopher Strachey (deceased), Leslie Lamport (still working for Microsoft), Joe Armstrong (very much still working on Erlang); but even so it is the content of the papers they write and the code that they have given us that matters.
