It can be useful in the selection process. Way back when I used to do the hiring and firing for a company, we needed a desktop support person. Of all the CVs I got through only one stood out, not because of the experience or qualifications (which were all on a par), but because the person's hobbies included Ballroom Dancing. My view was, if he could go out onto a dance floor, dressed in a, to me, silly outfit and dance then he wouldn't have any problem walking up to a user at their desk to fix an issue.
Sure enough I interviewed him and took him on and he was one of the best desktop support people I have worked with.
