At techcrunch you miss 90 % of startups. You only get to read about companies the editors believe are different. HERE, we are all the same. My karma could be 2 and still my story or startup could be on top of the listing.
TC is awful and they're not an aggregator :( They're just posting PR stuff that companies send them. GigaOM is so much better... at least he looks at stuff more critically and says what he thinks.
TC doesn't have the great hacker-in-the-trenches commenters that news.yc has. It was always so useful to see what my peers have to say about the nitty gritty stuff of startup building, share experiences/advice/etc...
