30 Facts People Shared In This “Today I Learned” Group

Today I learned that there’s a place online where people can share all of the neat, random, and interesting things with each other and the submissions are so great, we had to share them with you.

When I was in school I always thought that after I graduate, I must have learned everything there is to learn but we all know that’s ridiculous. We should learn something new every day, or at least try to.

So why not start with Reddit’s “Today I Learned” and then you’ll have something new to bring up the next time you’re at a wedding that you don’t know anyone at.
