Last week, we reported Google changed how Google Webmaster Tools reports links from subdomains.
There was speculation that this change also meant that Google has changed how they handle subdomains for ranking purposes. That is not true.
Googler, Pierre Far said in a Google + post that this is not true. He said it is only related to reporting within Google Webmaster Tools and not for how Google handles ranking.
Let me quote Pierre:
Glad Google cleared that up.
