I have been fairly active on Reddit for one year, as a registered member. Today is considered my first cake day, or anniversary there.
What have I learned? Whatever your interest is, you can likely find a sub reddit group there for it. I belong to a prepper group there. There are some fun sub groups that are much more popular. I actually was first made aware of Reddit by a friend who belongs to the group: AITA, Am I the a**h***? Another sub group is called Petty Revenge where people tell about experiences they've had and what they did in response. Another interesting group is Neighbors from hell. Just like here, you choose what topics you are interested in, join those groups and get notices on a home page when there are posts in your groups.
I see groups for herbalism, herbs, homesteading, and much more!
Like this forum, topics are posted, and then people can respond, ask questions, give input.
