"I’m responsible for the SUP implementation on OurDoings, and would like to respond to Stephen Kaye’s valid question about whether real time is desirable for all kinds of information. I was asking myself the same question while implementing SUP. OurDoings was originally designed for people who had a hard time keeping up with their photo sharing. You can upload photos in huge numbers and it organizes them for you by date, in a blog-like format. If you’ve waited for months to share them, who cares how fast they go out to your social network via FriendFeed? It actually does help psychologically. The closer a reward is to an action, the better it reinforces it. When your social network likes or comments on what you’ve shared, that’s a reward. The sooner that reward happens, the better it reinforces the action of sharing. And for busy people (e.g. parents) who might otherwise disappear from their friends’ lives, sharing needs to be encouraged." - Bruce Lewis
