Now I tread carefully because you never know what kind of propaganda is being spread around.
People say stick to the subreddit. But I think that's silly. If the core of Reddit is rotten, then the subreddit themselves will be affected. It has happened to places I visit like /r/environment. There is a constant barrage of non-environmentally friendly comments. Not enough to change the overall makeup of the subreddit, but enough to make you wonder who is on the other side of the screen voting or down voting on stories.
Then there are places like /r/technology, which is almost intolerable to me at times.
People say I am paranoid, but like with anything, if you know a place well and visit it for years, you can sense when things change.
And yes my opinion is subjective, but this is a subjective topic.
