Get out and comment. Comment as much as you can. Once you get to 1000 points, you can start posting memes as a comment; you're more likely to get replies that way.
The more posts you comment on, the more likely you are to get a conversation going.
Once you start building a rapport with other users, they'll start going to your profile to check out your posts.
A lot of times, when your post features it gets featured with a handful of others or it features at a time when nobody sees it and it gets buried.
Hope this helps. Good luck and happy meme-ing.
Also, I gave an upvote to your posts ????
