I completely and totally disagree. Reddit is of no benefit for anything you could just Google. Reddit's commenting dynamics create a false consensus around whatever the first thing that a bunch of people who Googled it can not disagree to. That's bad enough but when you start talking about subjects that have any degree of subjectiveness people's desire to have their world view confirmed abounds and it becomes even worse.
Pick a subject you're very familiar with the nuances of and start sorting comments by best, go straight to the bottom and among the low quality junk you'll find that there are tons of valid and well informed opinions that get rejected because they required more nuanced thought to understand than a bunch of amateurs who just googled it could muster or wasn't 100% compatible with the ideology of the group at large.
The net effect is that you get "if you just Googled it yourself" quality answers (pretty much every "open to the internet riff raff at large" platform has this problem to an extent) but sent though a filter that removes a substantial fraction of the opinions from people who actually know what they're talking about. Frankly the chans are better in this regard because the only mechanism for disagreement is to reply and the content of replies makes the nature of agreement/disagreement pretty obvious.
As bad as HN is about rejecting anything that doesn't fit it's narrow ideology about how the world works it at least usually doesn't reject things if they're technically correct. The same cannot be said for Reddit.
If you want professional advice you need to go somewhere with some sort of permanence and a higher bar to entry (i.e. the people who wind up there have actually care enough about the subject that they sought the place out), traditionally forums fill this role.
