Found a site worth mentioning, I was wondering what other memes might be out there that I am missing and found a site dedicated to compiling all the memes.
If you host a meme you can have it listed on their site. If you are looking for something to blog about you can be prompted by some of the meme topics. And, if you already wrote a post that you want to "get out there" you can probably find somewhere to link to it.
Whatever your motivation, check out the Daily Meme.
