A pony named Foal Papers has taken up My Little Pony's official tweeted challenge of getting the twitter tag #MyLittlePony to trending status. Wondering what that is, or why you should care? Foal Papers has written a nicely-formatted (lovely typesetting, by the way) Tumblr post that explains everything quite nicely.
Find that here.
Basically, what you need to know is: between 6AM and 10AM on Saturday, you should use that hashtag. Twitter will count the occurrences of it and hopefully we can get it to 'trending' status.
There's more info in the post. Get cracking!
