I also appreciate the open nature of Reddit. No account is required if you just want to read, and you don't need to be first "approved" to most subreddits to be able to contribute. No "real-name" policies that often do more harm than good either.

While Facebook by default erects walls around content, Reddit by default promotes the free sharing and equal access to information, which resonates much more with the original promise and mission of the internet.

It's encouraging to see Reddit overtaking Facebook in popularity at a time when the freedoms of the internet are often under attack. Yes, Reddit has its flaws, but in the end, it is one of the best defenses that we have.
