Yeah, I finally tried out NewsBlur yesterday after waiting as long as possible to decide on a replacement. There's a lot going on there. I think I've more or less figured out what it's all for and how to navigate around, but one thing is still bugging me -- what's that orange triangle on the left of the feed area, that follows the cursor around unless you "lock" it, for?! Totally unexplained ux element.
Yes, this. I was confused by it too until I uncovered that in a GetSatisfaction thread. If you lock it about 1/4 of the way from the top, the auto mark-read behavior is like GReader.
It should probably default to being locked...
One of my favorite things about Newsblur is how minutely configurable it is, but I think all of that is probably throwing off new users.
