"I particularly like the way this happened too," one person wrote on Reddit. "One act of kindness, with no anticipation of reward, ends up accomplishing something that is a reward in its own right."
Another person wrote about ordering 144 individually packaged toothbrushes for the center, and others wanted to drop off donations.
"It came as a little bit of a surprise to us when we started hearing about the post," Tulsa Day Center for the Homeless Executive Director Sandra Lewis told ABCNews.com today. "We've received over $400 in contributions for the program, which is pretty spectacular."
Lewis said that she recognized West when she saw him on TV. The support has come from all over the world, including donations from the U.K. and Spain, she said.
"Isn't that amazing?" Lewis asked. "It was so wonderful to see a positive story about a homeless person and a positive attitude from people about a homeless person. So often the things that we hear are negative."
She hopes that West will come back to the shelter so that the staff can help him with housing or any other needs he might have.
"It is just kind of one of those pay it forward moments where one person does something really, really helpful and then that chain reaction of people wanting to follow suit," Lewis said. "I thought it was pretty amazing."
