Yeah! At last Google shows most or all backlinks to sites I control. Webmaster central (a.k.a. Google Sitemaps) gives a relatively good impression of the links to your website. This is what most SEO’s should have been waiting for.

update:
Yesterday Google accidentally made it possible to check backlinks to pages outside the verified domain, just by entering the url in the address bar. After this beginner mistake Google took down the backlinks checker and fixed it. I just got time to check about twenty websites and download the CSV, but the data was definitely better than that of the Yahoo! backlink checker. Thanks Google!
