Personally, I come from a more technical background and in private life, I don't use many of the popular social media platforms intensively. The only one I am pretty active on is Reddit. As such, I have also seen most success on Reddit when it comes to social media marketing (to be fair, I haven't yet gotten REALLY started on the other ones).
I find that it also makes it very easy to target the correct audience (for our product at least) because of the numerous different subreddits and because you are less dependent on the favor of the algorithm or your number of followers than on other platforms.
What are your opinions/experiences?
