Page "History of Esperanto" Paragraph 22

Many Esperantists believe this declaration stabilising the language is a major reason why the Esperanto speaker community grew beyond the levels attained by other constructed languages and has developed a flourishing culture.

Other constructed languages have been hindered from developing a stable speaking community by continual tinkering.

Also, many developers of constructed languages have been possessive of their brain-children and have worked to prevent others from contributing to the language.

One such ultimately disastrous case was Schleyer's Volapük.

In contrast, Zamenhof declared that " Esperanto belongs to the Esperantists ", and moved to the background once the language was published, allowing others to share in the early development of the language.
