Why does acidity increase as you go down a group?

If a compound can donate protons or accept electrons (and lower pH) it's considered acidic correct? Doesn't electron affinity become more positive as you go down a group? And isn't electron affinity a measure of the energy released/required to add electrons? o_O

Also.. I wanted to clarify the trends I have been memorizing:

Atomic Radius: Increases RIGHT TO LEFT a period and DOWN a group.

Electronegativity: Increases LEFT TO RIGHT a period and UP a group.
Electron Affinity: Becomes more negative LEFT TO RIGHT a period and UP a group.
Ionization Energy: Increases LEFT TO RIGHT a period and UP a group (with 2nd I.E > 1st I.E)

Acidity: Increases LEFT TO RIGHT a period and DOWN a group? o_O
