One of the comments in the article links to a paper which describes the failure to replicate Bem's results: http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1699970
Good find! To expand slightly: They replicated one of Bem's nine studies and failed to replicate the result. The study they replicated did not involve erotic images.
Ben Goertzel has a rather long psi-related article in Humanity Plus Magazine, apparently prompted by the recent precognition study to be published in Journal of Personality and Social Psychology. He's arguing that psi is real and we should expect to see the results of this study replicated.
