Welcome to the hive.

If you make your own memes, #memehub is the place to post them.
If you don't make the meme, and you want to share it, post it in the notmymeme community, set the rewards to burn, and viola!, instant fame.
Not alot, but some.

People will find you if you put out 'good' content often.

They will also find you if you put out 'bad' content.
Plagiarism, id theft, reposting already posted stuff, spam comments, all will get you noticed real quick.

The quickest path to lasting fame here is 'good' original content.

Good luck.
