In my opinion you're confusing the the acceptance of Bitcoin as lost momentum and interest which is a mistake.  The media has had time to figure out what Bitcoin is and I think it's more that we are in a phase where people are understanding and accepting more then anything else.  This period of stagnation is not a surprise to many people and that is why your so confused and way off target but I can understand why you might make such a mistake if you haven't been really paying attention.
If by bubble you mean pointless dumps then yes I suspect so.
