I got pummeled by a handful of small time networking guys who think their one rack data center is hot shit and there is just no other way to do things than to buy Cisco and parrot what their sales guy says. I kid you not, one of them seriously was calling his Cisco sales guy and asking about some Cisco news, got some spin from his sales guy and, and then posting what his sales guy told him.... (dude even said he was doing that) I was done.
Technical, it's great to locate yourself on the map and get a compass - then you have to leverage outside sources to get to the destination.
Reddit's chronological weighting is a very big factor in this. If your comment comes a few minutes after a post, such as the time it takes to read the content of the post--or if it takes time to thoughtfully type out a response--it is scored vastly lower by the black box and is less likely to be seen and voted on.
There are certainly exceptions, but unless you already know a lot about the subject at hand it's very hard to pick them out among the deluge of jokes, smark, and people rapidly parroting the misconceptions of others.
The understanding of a lot of things are almost non-existent on reddit, or rather the people who know what they are talking about are buried by an algorithm that vastly prefers populist comments typed as quickly after OP as humanly (or robotically) possible. Of course this makes reading the article (or other posts) and having your comment visible mutually exclusive.
I didn't realize how little correct information was available on reddit until I became very specialized in a subject, went to that subject's sub, and saw that practically nobody there even knew the basics--yet they happily chat about the subject anyway, pretending they were experts. The rare exceptions were nearly invisible, lost in in-jokes and references.
Be-very-fucking-ware when asking advice about something you are unsure about on reddit, they will channel so much smoke up your ass you'll burp clouds. And once one person makes a confident declaration which is totally false or misunderstood--pretending they're some pro or expert--almost immediately every other guy in the thread is copy-pasting his response to every other instance of that question as quickly as they can to get points or whatever. It's silly.
For the record I try not to be so delusional as to believe I'm the only one who knows anything and everyone else is stupid--I'm totally average, lots of people are brighter than me. This is a systematic thing brought on accidentally by their forum design.
