Get those little fuzzy balls while you can.

Sunday's LDS Church semi-annual general conference, President Thomas S. Monson recounted the time he said he wanted members of the church perform an act of service as a birthday present to him.

Since then, he said, letters and other paraphernalia of what members have done have poured into his office, include a large jar full of soft little balls courtesy of a ward primary -- "warm fuzzies" -- that indicated an act of service performed for each ball.

On Twitter -- the growing microblogging site -- the so-called tweets were coming fast and furious about the need to do the same thing in individual homes. Even as thousands of members stuffed the LDS conference center in Salt Lake City and hundreds of thousands more watched the conference broadcast, other members were pushing the event to the forefront of social media. The search term "#ldsconf" remained among the most popular on Twitter over the weekend. Tweets flooded in, for example, when Monson spoke of the need for service.

They ranged from the need for the warm fuzzy jar to jabs at government. But drawing the most attention on Sunday was Elder Jeffery R. Holland, who used the majority of his time to give a direct and emotional testimony about the veracity of the church's Book of Mormon.

"I want it absolutely clear ... that I declared to the world in the most straightforward language I can summon that the Book of Mormon is true," Holland said.

The talk was followed by thousands of tweets about how powerful it was. "If you do anything else, watch Holland," wrote one person.

But even as the church's members streamed, tweeted, IM'd, listened and watched conference on every piece of media at their disposal, Elder Russell M. Nelson said the best kind of communication doesn't come with a cost.

"Even more amazing that modern technology is our opportunity to access information directly from heaven, without hardware, software or monthly service fees," he said.
