I'm not sure that's the right question to ask. In 2003, people asked "do we need another social network?" The answer was surely no.

There are countless sources of tech news, most of which are not particularly good (Sturgeon's Law I guess). If Sarah Lacy can manage to build a better version of what Techcrunch was at its best, that would be nice. It remains to be seen of course.
