I have integrated a feature to share items on ReadBurner without having to subscribe to the Feed first. Louis Gray led me to this idea with his recent article Add Items to Your Google Reader Link Blog Without Subscribing.
How does it works:
You hit the share button and then the Google Reader will open with only 1 item in it – the item you want to share. Instead of subscribing to the feed you just open the item, hit share and close the Google Reader. It’s a little bit complicated – but hey, it works 😉
What do you think? Should I make use of this feature and add some code to check things that you’ve already shared?
