I would love to see an option where I can select a default product to be my home page for folks like me who only work with one product within the community.
Unfortunately, the system doesn't have the option of allowing different home pages. The closest thing it has is to allow you to bookmark a specific area of the community, then you can see your bookmarks when you click on your avatar and view your profile.
Or, the old fashioned way is to put a bookmark in your browser to the area you want to go to.
Another option is to subscribe to the RSS feed of the area you are interested in.
