Not really. Half of people are barely literate. Maybe the top 10% have writing and language skills cogent and coherent enough to hang out on a website like this. So realistically we're talking about maybe 20% of the people you're interacting with. Possibly more, since this is the modern USENET where all the shape rotators hang out. People who can rotate shapes at all probably score at least that on tests.
