I have a question

How do people go about finding good blogs on Blogger like the ones I have been reading from friend's blogs? Is it just from other people's posts of these websites or is there a way to search them without looking through the (excuse my language) crappy ones to find the good ones? I can do the other people's posts, that works out great, but I know there MUST be people out there with other blogs that are good too. I mean, they can't ALL be like that one that I keep encountering when I click the "next" button, can they? (That one came up 4 times)
I did find one that I found interesting, it was on cooking for the diabetic. I don't eat sugar. Well, I try NOT to eat sugar. There God, you can erase that black mark by my name :-
I'm happy for any input. Thanks!
