“I consider, the more likely it seems that Safari’s Reading List is either going to have no noticeable effect on Instapaper, or it will improve sales dramatically. Time will tell.”
I agree. Most of the people who use the version built into Safari would not be customers. How many people dont use safari on the desktop? I think a bunch of geeks, most of Instapapers target, use Firefox and/or Chrome. In the end Instapaper is still better and I didn’t hear about offline reading in Safari. Also no easy social stuff that Instapaper has.
