There is actually an amazing amount of really good quality content out there, but as everybody on this thread has pointed out already, discoverability is a major issue. I often wonder how one would go about finding a site like the one you made if it hadn't been posted here, though I suppose "aggregator" is actually a decent search keyword that should (in theory) also lead to other good content. Presumably "blog aggregator" wouldn't be a particularly useful search term though.
