HS: Follow Them All!

HS'ers are always talking about their code inside HS and I get
excited enough to look their repos up. Then I got tired of
looking up individual HS-ers in every batch over Twitter and Github.
If I followed them all it would be easier to get feed data about their
activity and so I am writing this!
