G'day Robert (& list);

Personally, I think you should use any license you're happy with. I have 
a small political bias against GPL3 (there are some weird restrictions 
in there designed to "thwart evil-doers"), but I have no hassles 
implementing or using GPL2.

For your purposes, I would suggest the MIT license if you are just after 
credit being retained in derivatives, or MPL (Mozilla Public License) if 
you desire credit retained AND changes to remain in the open. MIT is GPL 
compatible (but can be modified without contributing back into the 
open); whereas MPL is not strictly GPL compatible (however it keeps 
changes in the open).
