I checked your comments out. I think people are down voting your comments. I occasionally say stuff that gets down voted but I have lots of up voted comments to. It's alright to have an opinion but more people need to agree with you than not. ;)

But if you want to get upvoted you need pretty useful comments with advice. and links don't hurt either. you can check out my comments by clicking on my username and get a feel for things the community found useful. I hope this didn't come off condescending. I struggled with it for a while.

Others may have better advice on finding good stories/news that get 100s of karma.
