Recently I've spent a little too much time thinking about open source licenses.
Whenever I start a new project I struggled to pick a license, there are dosens open source licenses that are all more or less the same. In fact worese than being the same many licenses that have the same goals are subtlety incompatible with one another.
Linus has expressed why he likes GPLv2 and not GPLv3. Even within BSD license there are diffrent versions which can be confusing.
The MIT license however is, short, simple, open, doesn't have lot's of diffrent variants and I was supprised to find it's the most popular license on GitHub so it's very well known.
