This is a minor issue, but it’s a little niggle that has been around for a while.
I have Newsblur open in a tab in Chrome permanently. All the way through the day it updates continuously as you would expect. I put my laptop in suspend at the end of the day, and then wake it up again in the morning.
Anything that came in overnight doesn’t appear in Newsblur, however long I wait. This is fixed with a quick ‘F5’ to refresh it, but it would be nice if it picked stuff up without have to force it to.
