Well, okay, but turn it round: what do you have to lose by listing the jobs? Some people will be convinced to sign up without them, but if you list them, some additional people will sign because they are interested in those jobs.
Maybe some that would have given you their CV would be put off if they see only listings for jobs they don't match - but they don't match them, so they're not going to help your business any time soon anyway. So: the ones you gain by not listing don't help you, and the ones you lose are the ones that would.
Having only a couple of jobs just makes you look small, not weak. But there are many small recruiting forms that do well - for example, one guy who I've used, Mark Ashton, only listed a couple of roles on his website[1]. But when I was a hirer he was still a great recruiter who found candidates that were matches, because he knew the market. As an individual, I still go to his website to see if there's anything of interest. (Okay, he seems to have changed his website and it doesn't show any jobs, so not as good a piece of evidence as I thought. But probably that's because he doesn't have a client right now, rather than because he wouldn't list them).
