I will start with an overview of the zoology of link homology. Then I will explain how to (non-trivially) categorify 1 via the so-called gl(1)-homology. I will use This homology theory to exhibit a new categorification of the Alexander polynomial. In time allows, I'll relate this to Heegaard--Floer homology and explain how this proves Dunfield--Gukov--Rasmussen's conjecture. In progress and joint with Anna Beliakova, Krzysztof Putyra and Emmanuel Wagner.
