I was prais­ing Friend­Feed a short month ago in these very pages, but I’ve come to real­ize that what Friend­Feed will nev­er replace Twit­ter and its ilk as long as it remains a most­ly pas­sive inter­face. Sure, it’s a great way to keep track of what’s hap­pen­ing with your friends as they use social media, but most of them don’t reg­u­lar­ly vis­it Friend­Feed to keep track of the con­ver­sa­tions that start there. Unless Friend­Feed can reverse the infos­tream and become a con­tent source, it’s des­tined to remain a repos­i­to­ry for the flot­sam and jet­sam of the infostream.
