that's not what makes something "web2", that's just good design practice.

web 2 was just a short form for 'i don't design like we did in 1997 when everything was new with spinning gifs'. this design style is a fad, because it's a fad that's evlolved from all the previous ones since 1997 with the gifs. soon enough there'll be a new fad which will be an evolution away from this look.

desing that way if you like it, but it's not the be all end all of good design.
