Is it just me or is the title "Sound Design" entirely ill-formed?
Speaking from 17 years of experience in audio production and engineering, background in band producing, advertisement and acoustics and vibration analysis, "Sound Design" does come out very, very narrow, "designing sound" applies to a very specific niche of synthesized sound, which is far from illustrative of the scope of this site so far. "Sound Design" implies "from the ground up" - you design the sound, therefore it applies only to synthesized sound, and doesn't apply to capturing and modifying sound and the associated workflow and toolchain, which seems the bulk of this site is all about.
Keeping in mind the topis addressed here, I'd say "digital audio" or "PC audio" or "sound engineering" is far more apt naming, I'd personally opt for the latter.
Are we married to "Sound Design beta"?
