I'm amazed no one has mentioned how beneficial it could be to find other people who review beers in a similar way that you might, in terms of how you like certain beers.
It's an invaluable tool when looking for new styles you might like, or new beers you want to go and try, especially when on a budget.
Sure, there are a lot of bad reviewers and bad reviews out there, so once you find those 5 or 10 people that you read consistently, you start aligning your palate for beer with theirs.
So if they like a particular beer, there is a big chance you'll like it too, and if they hate a beer, you likely will too, so why bother wasting the money it?
It works the other way too... you can even find when someone else hates a beer, that means you'll probably love it.
But this is much more rare...
Don't most of you have some friends you trust, and if they say they love it, you know you will too? That's the same as a review in my book, and a demonstration of my point.
Long live beer reviews, of the 5% that you can use to your advantage!
