I'm a bit late to the thread, but it's an interesting read.
I agree with many of the comments - especially getting books by photographers and looking through them and identifying the images that speak to you, then asking yourself why. After that you can ask why other photos don't have the same effect? If the photos are iconic (either the ones you like, or the ones you don't) there will be lots of discussion on the web and you can dig deeper to find out what the "experts" think, and why. You don't have to agree, but it's all good knowledge.
As stated earlier in the thread, it's also a wise thing to look at the photographs from the people who are giving you advice to see if you like their work. If you do, great. If not, well you may want to accordingly weight how much of their advice you then take on-board.
It may also be good to study the underlying principles of photography. Knowing what the ideals are (composition, colour theory, lighting, exposure etc etc etc) may help you figure out why some photos resonate with you and others don't, although for street photography we have to accept that much of this is outside our control. At least understanding these things will help us appreciate us the skill of a photographer who does manage to include some of them when possible.
We all like different photographers, the same as we like different food. Just because someone tells you something, or someone, is better than someone else doesn't make it real or right. It's just opinion. Like others on here, I'm not moved by some of the greats (and I've spent a lot of money on their books in order to discover this!) and I also agree that there is indeed plenty of emperor's new clothes stuff going on. But what's probably true, is that if we all got together and shared our favourites all of the greats would be loved by someone, probably a few people.
It's a shame that no-one wants to do critiques any more, I've been involved in critique groups in many things over the years - songs, stories, photos - and there is no better way of learning, both through doing a detailed critique yourself, and reading the critiques of others. We learn quickly the things that we miss, or indeed get wrong, in our own critiques as well as our own photos.
Lastly, the web is chock-full of good advice, poor advice, great photos, bad photos, with (seemingly) every man and his dog wanting to set up as a content-provider and make a living through telling you what you should do and why. Again, choose your mentors wisely. There a few very good street photography channels out there and an awful lot of bad ones.
Beyond that, I have no advice, because I feel like I'm only on the first few steps of this journey myself.
