The way I understand it, charging NiCds (NiCad is a brand name) before they are almost completely discharged allows crystals to build up in the cells which is this "memory" problem. Chargers that pulse charge help to prevent this (I've been told that some pulse chargers will actually break up the crystals and restore old cells somewhat), and "smart" chargers, like Bill pointed out, that discharge to a preset point first are even better.
The danger of discharging too far is that the cell may reverse polarity. I have never seen this happen, and I have abused my share of NiCd packs!
I'm going to surf for a few articles by respected RC modelling mags to see if there are any tips out there...
