Google search trend data seems to agree with you...

But might just be the initial excitement dying down.

Comparison with linkedin, flickr, reddit (us only):

Will be interesting to see if that is a real plateau or as you say just the fading of initial interest boom. Next six months should be telling.

It will also be interesting to see if they tie G+ into Ice Cream Sandwich or Jellybean somehow to help it snowball.

I love the way LinkedIn searches drop off at the end of each week. Makes sense since LinkedIn is for professional networking and people like to shutdown for the weekend.
