Go with BSD if you want people to do something with it. Unless you don't want for people to make closed source apps with it, then go with GPL.
Thanks for pointing this out guys. JK
I'm using the ISC license (https://en.wikipedia.org/wiki/ISC_license) which is equivalent to the 2-clause BSD, but does so with fewer and simpler words.
Also, the MIT license (https://en.wikipedia.org/wiki/MIT_license) is quite popular. It is also equivalent to the 2-clause BSD, but not quite as short as the more modern ISC license.
