Well, the world didn't end last weekend. There were countless rapture jokes thrown around last week and a whole new set this week. There is also a really good letter going around to the Christians that believed Camping's prediction. I have one more thought I'd like to add.
God works all things together for the good of those that love Him, including this. It is His great mercy that when His children believe a lie, He doesn't leave us there. He humbles us and shows us the truth. There have been plenty of times in my life where I have believed wrongly and the Lord corrected me. I'm sure there are many more to come. This particular correction involves a lot of public ridicule, and Satan specializes in converting humility to shame. But shame is a lie as well. There is NO CONDEMNATION for those who are in Christ. Go on knowing that Christ is refining you, slowly and painfully at times, into the image of His son. By showing you where you believed a lie, He is blessing you with more of Himself. I know because He's doing it in my life, too.
