It has been just over a year since Google opened the new Google help forums. The official date seemed to be the Google Talkabout forum in September 25, 2008, but most Google services didn't move over until later. The Google Webmaster Help forum didn't move until December 2008 and the Google Reader forum didn't move until last week.
Now, Google support forum profiles have not just questions asked, but also answered posts. So if you leave answers on other people's threads, they are included in the profile of the user. There is no RSS feed yet, but this is a major benefit to me and helping me bring you some of the best discussions in these forums. For example, see JohnMu's profile and you will see both questions he started, plus threads he replied to (but did not start).
Forum discussion continued in the original welcome thread at Google Webmaster Help.
