I imagine that when people see the Fundamentalist Mormons like the ones in Texas with bunches of wives and wearing weird XIX century dresses they assume that all Mormons do this, since there is no way to distinguish Mormons otherwise (unless there are two guys wearing white short sleeved shirts and neckties on bicycles cruising about).
Announcing the End of the World was always a problem for Christians, because of all that silly stuff in the Book of Revelation. There was a a guy named Miller, who got a whole bunch of people to give everything they owned away and to gather on a mountaintop on Oct 22, 1844. The world, as you might have suspected, did not end.Instead it began to rain. This was called "The Great Disappointment". Luckily, they were peaceful Christians, and so it was not known as "The Day We Pummeled and Thrashed that Lying Preacher".
I heard that Joseph Smith predicted the coming of Jesus on Smith's 85th birthday, but Smith was deceased by 1890 and apparently celebrating a specific birthday after one is dead does not count for predictions. It might be safe to assume that Jesus decided not to come to Smith's 85th birthday party at the specified place near Gallitin, MO. But I don't think that he named the place in that prediction.
I think that it is likely that to predict the end of the world or the Second Coming of Jesus in specific terms has NOT proven to be a good career move for preachers in general.
Here is a bunch of stuff about Smith and prophesies, and how they were all fulfilled, maybe were not really prophesies after all, and might have not been fulfilled, after all. It seems to have been hard for preachers in the 1900's to read all those Old Testament Prophets and not want to join them in predicting the future. Perhaps if they had proven more adept at curing the lame and the lepers or even at turning water into wine, this would not have been such an obsession for them.

Sort of like all the Young Pioneers in Cuba wanting to be like El Che, I guess. That was not a clever idea, because Cuba needs people who can do things that El Che was not good at, like growing rice, beans and coffee. Once a Revolution is won, there is no real need for revolutionaries.
There is a salt shortage in Cuba these days, so we could add making salt from sea water. I do not think that a tropical island surrounded by a salty ocean should suffer from a salt shortage.
I can see why "Church of Christ", "Christian Church" and other various similar names might be popular, being as Christ (as opposed to Jesus) was the main focus of the religion from the time of Paul.
