Yeah, if you expose the blot to a solution of RNAse you will loose a lot 
of signal, but blots are much more resistant to RNAse contamination 
floating around in a lab.  I've never had any problems with RNAse
contamination on a blot while I have had problems in RNA solutions.  
Adding RNAse to a hybridization mix will have more of an effect on the
RNA and I also feel that the RNAse molecules will interfere with hybridization
