This really depends on what your goals are. For example if you want a standard that is defined by your software to become an accepted and widely used world wide standard, then Apache or MIT may be a good license. If your application could use a lot more contributions, and most companies won't lose anything if they contribute back their modifications, then AGPL may be better. If you want to make some money off your software, then maybe a Free license isn't appropriate at all. Or maybe it is, if your software lends itself to making money off of side services (support, bespoke enhancements, paid plugin modules, etc).
