I see there's a lot of stumbling going on here. Is there still a limit to the friends you can have on Stumble Upon? I reached that limit years ago, got frustrated about it and left.
Correct me if I'm wrong, but that's just the limit on the number of friends that you can select to be your friend. You can still have an unlimited number of fans, or people who select you to be their friend.
That friends limit sucks and is one of the reasons why I don't use SU anymore. What am I supposed to do? Drop old friends when I get a new friend request? This limit to growth sucks big time.
