I can't stand how the Facebook feed updates in realtime. I read a bit, leave the tab, and when I come back to it it updates, so I have to find my place again (which I don't do, I just go "screw facebook" and close the tab ^^). The same for forums, if I want to see new or changed posts, I'll hit F5 -- and when I don't press F5, it's not because I forgot, but because I don't want to. Pressing it for me is a great way to make me go elsewhere; or in the case of facebook, to stay and resent you.

I don't need to know in realtime how many people are on my website. I need to know how many there were last week, and compare that with the week before that. Likewise, I don't really need to see a post the instant it was made. At least for me, the internet is great partly because people chose what they do how and at what pace, because it's more like a book and less like TV, and making it more like TV is not improvement.

This is not against the article per se, which I found very very interesting and thorough, just something I have to get off my chest in general. Though I really disagree with the article when it comes to the facebook feed, I think that should serve as an example for what not to do.

Please, think twice, and never be too proud to get rid of a shiny gimmick when it turns out it doesn't actually improve anything. Let's not sleepwalk to a baseline of stuff we just do because everybody does it and because it's technically more complex. As Einstein said, anyone can make stuff more complex :P
