I don't disagree. I think in general, there aren't enough professionals given the amount of crime that happens. This is a notable counter-example. The number of people working on this case professionally is/was staggering. Usually, though, it's a town detective that's got 20 cases open, and a few free eyeballs can definitely be of huge benefit. Some professional processes appear not to work well under this environment, too. For one, professional investigators compile a list of everyone who could be a suspect, and then disqualify them methodically and quickly. The reddit discussions established many potential suspects, but had no real way to disqualify them. The unfortunate result is that news media picked this up and the disqualifications came from public statements -- definitely not the way such a thing should work, and having your name publicly attached to a crime is really terrible. I'm not happy this happened, and I place blame primarily on the people who didn't bother to look at what was happening and instead took a picture with a box around someone as an indication that they were a suspect. Instead, it was just a picture meant to draw attention to something that seems suspicious for discussion, for cross references with other images, and with potential information people have that could be forwarded to the FBI as a tip. It also definitely showed that there's a very high noise to signal ratio in this, most likely due to the chaotic nature of an open forum like reddit. It's not ideal in this regard, but I wouldn't dismiss it out of hand because it has shown that it can be a valuable resource if used correctly.
