Reddit has always been about creating a place where people of all kinds can come together, be themselves and post/comment on anything you can think of. But what’s different about Reddit are the open discussions it allows people to engage with each other where they share common things such as experiences, share one another's knowledge, and support one another all in ways that don’t go through regular social media.
While Reddit continues to be an essential platform for community engagement as of 2025, on his subreddits for social causes, advocacy and social support groups. Whether it be a mental health based subreddit, a 100 % sustainable subreddit, or a subreddit aimed at speaking out for marginalized groups, Reddit provides a distinct possibility for all users to take part in productive, beneficial exchanges that enhance both the individual and the collective effort.
However a feature that’s defining of Reddit is its upvote/downvote system that gives people a voice in what content gets the visibility. This democratic approach ensures the best and most interesting topics hit the top and get the most talk and work done. This is readily undeniable as Reddit definitely acts as a social impact platform for which global communities would come together to change the world, discuss pressing social issues and support the needy.
For years, Facebook Groups have been a constant staple on the social media platform and while 2025 continued to be a valuable way for community engagement, they still were. Facebook itself has seen a move away from active users in comparison to it's heyday but Facebook Groups are still ever as relevant. It assembles such like minded individuals so they could come together, get insights, and take action on causes they care about.
Facebook Groups are places through which people can come together to plan for social good as part of a group dedicated to organizing around local environmental initiatives, raising awareness for mental health, or fundraising for global causes. The features of the platform promote deep engagement through allowing the ability to comment, post, host live discussions, and create such communities happening while working together for one thing.
The private spaces created inside of Facebook Groups are equally easy, but can be enormously important for those who need a sense of safety or anonymity — and therein can go a long way helping with topics like domestic violence, addiction recovery, etc. Facebook groups are a great example of a digital community platform that empowers inclusivity and action and as such, are a big part of the online social impact world.
