Stuck on a popular social media source? Crossword clue uncovered!

Once upon a time, there was a mischievous little character named Meme. Meme was always up to something funny, and loved to get into mischief. One day, Meme decided to create an Instagram and Twitter account, where he could share all of his hilarious pranks and jokes with the world.

As Meme started posting to his accounts, people quickly fell in love with his funny content. Soon, his accounts became very popular, and his followers couldn’t wait to see what he would come up with next.

But there was a problem. Meme was a very busy character – he didn’t have time to keep up with all of his followers and keep new content coming all the time. So, he decided to enlist the help of other funny characters like himself to help him out.

Meme created a special type of account and called it a “MemeAccount.” This account would be dedicated to sharing only the best and most popular memes from a variety of different creators, including himself.

Now, whenever people see the crossword clue “Source of some popular Instagram or Twitter postings,” they know that the answer must be “MemeAccount.” And they know that they can always count on Meme and his friends to bring a smile to their faces with their hilarious content.
