To get to the blogs hosted by SAS Institute, all you need to do is go here. I have to say that there is quite a spread of subject matter ranging from the high level business strategy offerings through to detailed snippets for SAS programmers. There seems to be a lot here for anyone interested in SAS and business intelligence. I must take a longer look.
Update: I have since discovered a central listing of SAS Institute RSS feeds. The list is well worth your perusal.
