I've seen Reddit do some awesome things like sending a child with cancer a pizza party because she requested it and they'll promote the unknown to the known out of the goodness of their upvotes.
I've also seen Reddit be awful. R/atheism, r/politics and r/news are three of the worst places on that site. They're so heavily bias it's borderline pathetic. R/atheism shouldn't be about promoting religion, but it shouldn't be about bashing religion (or mainly Christians) over and over again. You'd think a group of people that state they're a positive force would be such, but that subreddit isn't. With r/politics and r/news one expects some sort of balance, but there's nothing like that. Those two subreddits are so left leaning they could rename it r/liberal and no one would be able to tell the difference.
R/movies has it's own problems such as constantly promoting the boring films City of God, Requiem for a Dream and anything by Quentin Tarantino. Because Tarantino can do no wrong. You can't have an honest discussion on why these things suck without people going balistic. Oh, and never ever speak ill of the Dark Knight. That's the holly grail.
The great thing about Reddit is that there are tons and tons of subreddits that could pertain to almost anything you're into. Which is great and not so great. Some of the subreddits that have gotten Reddit into trouble have cease to exist, and some still linger around.
When you see NSFW (Not Safe For Work) that's a huge warning of do not open this if people are around that you don't want them seeing you looking at naughty naughty things. Just a warning.
I can handle bias and hatred for my views. That's fine. What makes me give Reddit 3 stars instead of four or five is that the voting system rigs everything. I think they need to change the system because it sucks. They need to make it where no one can get negative votes. Meaning once you reach zero... that's the bottom. The entire negative thing is a way for those who can't stand people having a different view roll around in like pigs in their own filth.
It turns into the mob with the upvotes and downvotes. YOU HURT MY FEELERS and my MORAL RIGHT... I gunna go and get all my buddies to hate on you.
I want to tell people about Reddit and how great it is, but it's not. And I don't think it ever will. I do like it because it sometimes gets me laughing or awwing or thinking. BUT... for the most part what makes the front page is mostly trashy and chauvinistic. If Reddit is the front page of the internet, we are all doomed because they don't pay attention to anything important going on in this world. They care more about Snowden than they do about what's actually damaging to their way of life. OHNO the government is spying on us... but really, when have they not spied on us? It is awful, but do you really think that you remove the NSA that another government agency won't take its place? Or a new agency won't take its place?
Reddit would be better if it fixed the upvote/downvote crappy system, the bias in several subreddits that shouldn't be and get more informed subscribers. Until then, I'm sticking with 3 stars and that's being overly generous as is.
