This bug has been bugging me for some time, so now I'm filing it:
On the community Overview-Page (http://www.sap.com/community.html), there are some featured blogs.
But: they don't display the authors Avatar, which they should!
(If the user would not have an Avatar, this would be fine - but if you follow the link, you see there is one -> so it should be displayed! (important for recognition)
