Louis Gray on the end of Friendfeed

One of the amazing things about FF was that you could stand in the full stream and watch snippets of the global conversation float past every 5 seconds or so.

It's also reminded me about a long standing FAQ about G+. The Profile.About.Links YASN-Roll really ought to grab the content and feeds from those links and present them somehow. Not by auto-generating posts but perhaps filling another tab on the profile. It's still a missing piece in the Apps puzzle to aggregate all the posts and all the comments and conversations across all the platforms. The Buzz problem (and FF problem) was the potential for spammy abuse. So the answer is to make it private to the profile pages so you only get to see it if you specifically go and look.

The other challenge is that when FF was built everybody, but everybody, produced RSS/Atom feeds so there was generally something to pick up and aggregate. But then location apps like Foursquare stopped doing it. And shortly after, the major platforms stopped as well, requiring authentication, went to custom formats and generally stopped playing ball. In some ways, FF was the peak of the Web 2.0 dream of open common formats before the tide rolled back.
