Liked the idea and used it initially, but it gets tired quickly, due to the implementation detail. When you see a recommendation, you have to open the article in order to Read Later. So it takes at least a few seconds for every recommendation. I often want to use the feature before a flight, where I want to add 10 or so articles. If you're on a 2.5G or 3G network, that means clicking on the recommendation, waiting 20 or 30 seconds, then clicking on the next one.

If Marco's reading, please add a "Read Later" button against the recommendation (possible on desktop with an extension).

I follow a handful of people on Instapaper and check the friends list for new content now and again, but rarely do I see anything there.

It's like I'm the only one who regularly "likes" the best articles I'm reading. I wish this weren't the case.

Same here. I'm following everyone Instapaper could find in my contacts (six people, if I recall) but I've never seen any of them like an article.

I completely respect Marco's goal of not building yet-another-social-network, but it is true that the social features are so minimal that I never really use them. I don't need Instapaper to be a social network, and I don't need it suggesting that I that I read something new ever five minutes, but if there were a a few 'suggested reads' instead of the 'social bar', I wouldn't complain ;)

never used the social sharing features, expect to maybe post an article to Facebook once. Its funny, its the opposite of Buzz. Marco realizes that people view Instapaper as a mainly private place, that on occasion a person wants to share something from. This is also the function gmail accounts play in many peoples lives, which is why buzz was not well received.
