Yes, this is about the "toy" construction sets of the Danish company.
I think it's perfectly legitimate to indulge in this type of hobby, just as much as it's OK to collect stamps, waste your life watching football on TV or solve Sudoku puzzles.
Playing with Lego will at least teach you something about mechanics.
I mention here once: "Lego" is a trademark of The Lego Group. This site does not endorse The Lego Group nor does it receive endorsement from it. It is just for fun.
And believe it or not, but there are "crazier" people around:
LDraw is devoted to virtual Lego
There is a Lego Maniac's Webring
Bill Ward has some Lego stuff…
And before plastic took over, there was the equally interesting metal Meccano.
