Meme aggregators are online platforms that collect and display a variety of memes from different sources. They serve as a central hub where users can browse, share, and enjoy humorous images, videos, and text-based content. These platforms often categorize memes by themes or trends, making it easier for users to find content that interests them. Many meme aggregators allow users to submit their own creations, fostering a community of meme enthusiasts. Popular examples of meme aggregators include websites like Reddit and Imgur, where users can upvote or downvote content, influencing what gets featured prominently on the site.
