I've skimmed through the sub-reddit. He means that they are absolute in ways that are simply not true and could discourage a newbe.

That said, IMHO it's better to ask then to hold it to yourself. Here or on Reddit doesn't matter.

It's good to keep in mind that there are infinitely diversified ways through which people achieved "a successful career" (whatever that means).

"It's easy to get a job in programming. If you are having problems you must be a moron. If you can't find a job, it must be your personality." ...But that's the whole point of asking for help. We want to be programmers and we want jobs, not to be treated like we're trying to take advantage of people. It's also a huge circlejerk, people are just gloating about how successful they are and picking on those who didn't get as lucky.
