The review system for plugins is antiquated. Before an end-user can leave a review for a plugin, they must first register for a WordPress.org forum account.

It's 2016. Regular people don't use forums.

I have one plugin on the repository. If I relied on the plugin's official support forum for end-user feedback, I'd know next to nothing to what people using my plugin had issues with. Again, most people don't have forum accounts. I found it a lot easier to include my email address and eventually my phone number in the plugin if an when people have questions.

People should be able to leave reviews with their Facebook and Linkedin accounts.
