Some nice ideas here.
I've always been confused by the way Instagram feed works.
Good stuff Allan, I think shifting the usual tabbed navigation to the top as well (like twitterific 5) would complete this into a pretty easy to use and understand layout.
So if I browse twitter, everything I've already read would be at the top and then I would have to scroll down to see new things? I don't see how this works with large amounts of posts. The reason for reverse chronological is for the instant gratification of new content. Chronological works well when it comes to understand the order of a conversation or discussion (i.e. forums). However I think a majority of the time the user who is participating is going to be up to speed, so the default desired orientation would be what is the latest that has happened since I last engaged with the product. I could see things getting repetitive pretty quick if your entire experience is always about seeing something you've read weeks ago and having to scroll to get to the latest.
I think you have misinterpreted my post, probably because it's a bit confusing. But to your point of -
"I could see things getting repetitive pretty quick if your entire experience is always about seeing something you've read weeks ago and having to scroll to get to the latest."
Solution B is actually the complete anti-thesis of that.
So yeah, with twitter, everything you read would be at the top and the newest content would be below, and you would have to scroll down to get new content. Which in fact means you're always getting new content and pushing old content away from you. (Because now your pushing to refresh rather than pulling to refresh on the top) The only flaw here is that this interaction model is more beneficial for active users rather than for more casual ones.
Ah ok, so you're saying when I log into twitter the first tweet I would see would be the oldest of the newest that I haven't seen? Then as I scroll down I see things all the way to the newest post of them all.
So with casual users, they would be tweets from 1 week ago, but as they scroll down they would eventually get to 1 minute ago.
I will definitely think about this more, thanks for the clarification
