There’s one difference. Mine doesn’t save the page, it just pretends to. And that’s good enough.
I use instapaper a lot. I think it’s a fantastic service. No longer do I have a hundred tabs open to web pages I intend to read at some point before closing the browser. I can push them to instapaper and read them on my commute instead in a calm stripped down format. It works great.
But I find far more things that look interesting than I have time to read. Currently I have 4051 unread links. I had to write some code to find that out because instapaper doesn’t have an unread count anywhere. That lack of unread count is the best feature.
That will simplify your reading list immensely! Dan has made his Instapaper Placebo available for everyone to use. Link -via Not Exactly Rocket Science
