Is the Stack Directory link dofollow or nofollow?

Why does Stack Directory have a DR of 43 but an LDS of 2.2?
Domain Rating measures a site's own backlink authority. LDS measures how much of that authority actually reaches you. Stack Directory has an estimated 83,586 outbound links, which dilutes the equity passed per link. Combined with the nofollow status, this produces an LDS of 2.2 out of 10.
