I think my 'timeline' should be representative of photos I've uploaded, posts I've made that I want to highlight and events I went to. My 'wall' should be a straight-forward top-to-bottom feed of stuff I've posted and stuff people are sharing with me.
I hate the timeline, as I can't track two columns, and probably wouldn't like a grid also for the same reason.
I logged in to Facebook a minute a go just out of curiousity, and struggle to actually find my homepage, first I get badgered by Facebook, I then accidentally stumble upon my Timeline (which I hate), I then click the Facebook logo to go to a homepage, which happens to be a feed - or rather what I deem my own homepage. Confused! And it happens every time.
I really only ever want that to be on most recent.
My other problem with Facebook interface is that I just don't know where to go to "do stuff" - eg: if I want to unlike a company page. There's a bunch of little icons in the top blue bar (10 clickable things in that bar), and then there is the list down the LHS, and the almost hidden follow / report this post button.
I do like the fact that it's being refined; I notice the occasional difference. And the new privacy announcements were clear enough.
I guess I don't use FB like most people use FB. I only have less than 50 friends and I don't like a bunch of products or companies.
As an archive it's great, you can exactly see what someone liked/posted in previous months, but it's not a feed, and that's what I would like someone's profile to be, a feed of his activity.
