Reddit is an open site where people can create subsections called subreddits. Each subreddit is free to administrate their part of the site as they wish. This is certainly a novel idea, however, like the earning mod powers idea of stackexchange sites such as stackoverflow/superuser/etc this doesn't work. Yes, these quotes are cherry picked, and not all of reddit is bad. However, you will find a lot of this in the default subreddits that people automatically are signed up for when they register for the site. These quotes are also taken from different subreddits, usually those that are the default. You can find some solace if you remove all default subreddits (or don't comment in those) and only stick to obscure/small subreddits like ones about underwater basket weaving.
There was a post about someone who worked hard to post tutorial videos about C++. This was naturally meet with lots of criticism. My saying is that if you have high criticism of a work you better be able to present work that you have done that is better than the work you are critiquing. Or at the very least be prepared to submit some (small) number of changes to make it better.
It appears that people are quick to judge, but don't want to actually offer help:
There is a more popular site out there for C++ that is constant shunned for information contained on the site. That site is cplusplus.com. There appears to be quite a number of people who parrot the same thing contains missing or inaccurate information
But why? What is wrong? (Stay tuned for more information on this on a next episode of "tales from the internet")
Those who ask for help are often meet with disrespect. Now everyone is as familiar with the functionality of reddit as others. Most likely this person is really struggling and just popped in for some one time help.
And generally just filled with immature people:
There are even people on reddit would be more than happy to tell you what they think of your sexual preference.
This was probably the worst comment ever. Someone's daughter attempted suicide and this was the only comment he could think of.
Or how about when someone of the open source community is killed?
There are also people who have very little experience mock those who offer their own advice
Edit: They also get an "F" in website security:
