@liaizon@clacke@mike@kajkandler Here's my best guess: not enough client software used it (just StatusNet and Buzz and Cliqset), so it wasn't valuable for publishers. Without support for feedback through Salmon, it was one-way syndication. And it was hard to find and subscribe to feeds. Our clients made you find the right Tumblr URL, instead of saying "fred179 on Tumblr". My company went out of business around 2013, so that didn't help, either.
