I often read in the MSDN Forums but I will read more often because now there's a client application available:

"After many months of hard work we are proud to announce the availability of our first CTP of the Microsoft Forums Client. Much of the work for this CTP is in foundational code that will let us build the rest of the application, but we hope that this first preview will let you see what direction we're heading in, and also give you a chance to give us feedback!
Things that work in this CTP:

• Getting the list of available forums
• Subscribing to forums you're interested in
• Manually (by right click menu) synchronizing the Question and General Discussion threads in a forum
• Reading posts that have been synchronized
• Hierarchical (threaded) view of conversations"
