Though I've been tempted to modify the subject line to include not my name but subject info, I'm pretty sure I never have on PM. This is because SuperSearch lacks authorship or navigational functionality, so the length of the title is the only way to differentiate.

Of course tye and merlyn have Another Way To Do It, for similar reason (i.e., self-defense). If I had my druthers I'd say if you must, change the right-hand side (say append " -mattr" to the subject on the right, if you must) so we get to keep the visual differentiation "functionality" provided by the indented width of "Re: " vs. "Re: Re:". But much more satisfying to enhance the relatively simple search engine output.

If SuperSearch is improved there will be less need to police the memes which of course ain't fun and ultimately is difficult, is time-consuming, and highlights the problem of highly individual monks (TMTOWTDI) coexisting in a media space which paradoxically does not promote ways to enhance one's navigational and information-theoretic experience. ahem.

Oh, there's another quick answer too - Smileys! (or Emoticons since they are way advanced in Japan anyway especially with a raft of two-byte symbols, and provide a conversational context). You can get an idea from popKmart, especially if your browser displays Japanese. Less bandwidth than an icon needs, and you can search by it to find wacky people. I don't know what happens if you eval it as a regex though..
