uhh, I don't think making speedcubing popular would be awesome. It wouldn't be recognized as a talent, but as a sport that everybody plays, like football (american and international versions).
What's wrong with that? (Don't be so elitist.

)
Plus, I really doubt it would ever become even 1% as popular.
1. People don't have the patience.
2. People don't have the interest.
I think as long as people are aware of cubing, it is good. Face it, not everyone is going to get addicted. Generating interesting is much harder than taking "stupid" questions from the occasional noob.
For every person saying, "wats the bestest cuba?", you have over 100 people saying, "This $hit is too tough for me. It's boring."
