Using that EXACT SHAPE for Twitter will expose thousands of extra people to your memes
Think of it as reading a billboard as you drive on the highway. Twitter is the highway, the billboard is the space you get to advertise. Don't hide your message!! You want all the "drivers" to at least SEE it.
10,000 people might see your "billboard" in a day but only 5 might take it a step further/click to expand. If people can't see the whole message very few will click it & even less will like or retweet it.
Black blank attached is the right proportion also
Don't step on your own neck
BEAM YOUR MESSAGE!!
