Haha, I thought you was going to question my thoughts! Phew..
I take it or leave it and mostly do a second check somewhere else for verification, just to be sure.
For general information, I would. If I would write a thesis and the like, it would be a good guide on where to look but I will not rely on it.
Not all of it.
I just look up things for quick facts. If I was going to be writing a paper or doing actual research, I would not use it.
