How can I share my Google Play wish list with other people?
You can use Changelog Droid app which featured one touch functionality to import your complete wish list into so called observed apps category and then you can export your observed apps to SD card (Preferences, Export/Import, Export/Import observed apps) and sent this file (/sdcard/cd_observed.json) to your friends which can import your observed list into their Changelog Droid. Yes they should install this app too, but this app is so good that they will be glad to use it anyway :)

For a few items in a wish list it is an overkill, but I have over one hundred apps in my wish list so in such a situation Changelog Droid is the acceptable way to realize sharing my complete wish list.
