Just now I used the classic "OH NO! Anyway" meme from Jeremy Clarkson. How many folks might have uploaded that before?

What if Piefed housed, or linked to some kind of service, that had a meme search.

This resolves 2 issues.

1. Interactivity is more fun and easier for users.
2. You can deduplicate storage. You'll no longer have 500 people uploading the same "OH NO! Anyway..." memes. This would also allow custom meme from other instances that could then be shared and grow the pool of built in memes, potentially deduping across all Piefed instances.
