I'm of a mixed mind on this subject. I do enjoy the clues and hints, mostly because I love coming to the forums and talking about it with you guys. They also help me get through the long days of Summer, which has never been my favorite time of year (nerdy, pale, slightly asthmatic, overweight...no, Summer is not good to me). The build up is so exciting, my anticipation has never been diminished by a few spoilers.
That being said, going into a house with little to no knowledge about what's coming is pretty darned intimidating. It doesn't happen often, but last year I made it to Catacombs with very little actual info as to what was going on in the house. It was transcendental, I tell you.
