I just added my Like to Corvida's blog post about email (http://friendfeed.com/e...), but I didn't see it pop back up to the top of my FriendFeed screen. What drives the logic? - Hutch Carpenter

Maybe it's time sensitive. 1 hour ago..maybe not. - Hao Chen

From what I have seen, it only pops to the top on a page refresh, not the inline updates. - Rob Diana

Julian - but there are times I Like something and is does bounce to the top. Maybe Hao is hitting on it - there's some sort of time element. - Hutch Carpenter

Rob - I did hit the refresh button after the Like. Corvida's entry didn't appear though. At least not in my FriendFeed. Maybe for others? - Hutch Carpenter

I think the FF devs have added a time var -- older items don't pop up if you like them or even if you comment, I think. Probably because some were complaining about "old" items resurfacing. - Sprague D

Sprague D - I'm going to go comment on Corvida entry to see what happens. Back in a second. - Hutch Carpenter

And there it is, at the top of my FriendFeed with the comment. - Hutch Carpenter

it's just like a forum.... it's not a feed reader - Stefan Hayden

I've been tracking the bump logic for a month or so now, and this is what I've found out: likes will stop bumping a story after a certain amount of time, and comments will always bump to the top if either a) it's your story, b) it's someone you're subscribed to's story, or c) it's a FoaF AND a friend of yours comments on the story AND it's the first time your friend commented on the story. Everyone else's comments won't bump it. For scenario c, Paul had mentioned to me that a fix for it was in the works. - Mark Trapp

I seriously disliked it, at first. But when reading it in Twhirl, I really like the forum idea. - Bradley McSpinn

@Michael - that is a good observation. A subtle way to manage what's relevant to you. But my comment on her entry did bounce it back to the top, whereas the Like didn't. Hmm... - Hutch Carpenter

Great info Mark. The subtleties of FriendFeed. So powerful. - Hutch Carpenter

FF clusters items i.e. FF items are clustered, google reader items are clustered etc. So if you don't have a like or comment for your item, if you add a new item of the same kind it will push the cluster to the top and push your item on top as well. I have seen this for folks who twitter a lot. Their twitters always bubble to the top. - Atul Arora

There's a lot of stuff in the feed logic of Friendfeed that once you figure out winds up being a "holy crap, that's genius!" moment. It'd be cool if they had a "For Nerds" page, that describes why things happen in a certain way on Friendfeed, although I guess that's really their collection of trade secrets at this point. - Mark Trapp

I know this isn't the case with Hutch's instance, but if you like/comment on a FOAF post, it doesn't bounce up in your timeline - Shey, Jamaican of FF
