I agree... always try not to use them.
A few hints, though, if other people do use the codes. This might not pin down the exact airfield, but it'll help at least pin down the area.
UK codes all start with EG - you probably knew that already. The next letter, though, gives you a good idea what part of the country it's in. For example:
EGLx = west London
EGKx = south of London
EGHx = south coast, Solent
EGPx = Scotland
I'm sure there are exceptions to this, but at least if people start talking about EGKA and EGKK (hi Fuji, BRL

) I know they're talking about somewhere to the south of London....
