If a person, say an author, is well spoken and writes a lot of books, he is called prolific. But, an ordinary person who writes well, but rarely and not in detail... he shall be referred to as amateurlific. He can carry on a written conversation fairly well, but the castle he builds with his prose tend to most often be made of sand. He fails to write enough detail, but fortunately for his readers, he chooses to write infrequently so they let him get away with it.
