Planet SharePoint has a feed with 200+ active blogs providing some great content. http://www.planetsharepoint.org/

Go to www.sharepoint2010blogger.com, At least 10-20 Posts weekly.

I use a newsreader and every time I see a good SharePoint blog (like the ones listed above) I subscribe to that blogs RSS feed. If I see something that I want to bookmark or that is worthy of sharing, I share it on my friendfeed at http://www.friendfeed.com/therobman. There are others who do the same thing. If you suscribe to one of our feeds that is a good source of info. To put it in perspective, my reader picks up 100-120 articles per day (not all SharePoint related) and I share on average 3-5 daily.
Some other sites that I find useful are cmswire.com (frequent posts about SharePoint, related products and competitive products) and codeproject.com (has some SharePoint related articles and sample code from time-to-time).
For news, go to bing.com's news tab and search on SharePoint. Then click the "News Alerts" link and subscribe to it. You'll receive a daily email with all of the places SharePoint showed up in the news that day.
