The only stupid question is the one that is not asked. As far as I know, RSA keys required licence to be used, so GnuPG favored DSA and Elgamal combination, since they were free. Finally, RSA keys became free and got included in free software. So far, it would be almost the same to use one or the other option, _but_: DSA keys used to have max size of 1024 bits, which by today standards are too short. DSA2 standard allows bigger keys, but may cause trouble with legacy software. IIRC, RSA has been around in free software for longer time than DSA2, so it is less likely to have problems. Of course, there are no guarantees you won't find somebody using a really old implementation of OpenPGP. And there is something about hash algoritms and DSA, so I would chose RSA and forget about it. As Robert J. Hansen said, the defaults are good, so don't change them unless you know what you are doing.
