Just did some mental arithmetic
50,000 words @ 6 characters per word (average) = 300,000 characters
300,000 characters + 50,000 spaces = 350,000 chars
350,000 characters @ 140 characters per tweet = 2,500 tweets
Divide that by 30, and you get 83.3 tweets per day - or 83 tweets per day, with 84 every third day and every tweet would have to hit 140 characters, and hit the 6 character word average.
Something tells me this way madness lies
