My go-to tech blogs are Engadget, Gizmodo, and occasionally The Verge. Kotaku is good for all around gaming news.
Many would say that Gawker sites (Gizmodo, Kotaku) aren't very good, as they've been known to employ poor writers and utilize manipulative post titles, but they're a great place to start, are very good about sourcing their content, and throw in some posts about other topics as well.
