When does introducing simplicity or constraint in design improve experience

From iPhone to sites like Fotolog (where you can only post one picture a day), constraint of design drives the user experience, and can also create popularity. Adam at Fotolog (and Scott) described how the constraint (or simplicity) of Just One Foto keeps the editorial imperative high, and it keeps the community different from Flickr (where you can post a HUGE number of pictures at any time). Communities like VOX where prompting people with the “Question of the Day” gives people something to blog about, in case the community member feels frozen or writer’s block – this ‘constraint’ bounds the experience and gives a place for writers to start.
Simplicity – making things easier for people to get over pain of adoption. People get overwhelmed with too many choices.

Skype – hard but gives people way to make free phone calls so people use it.

Adam – fotolog – doesn’t deny the appeal of the long tail, but too much or too many will reduce usage.

Pip Coburn’s model about getting people over pain of adoption – by giving them value.

Whether you call it restrictions, constraints, or simplicity, there’s something that helps people get over that pain of adoption. Rules vs Guidelines.

John B. – Everyone thinks they want infinite choice but it turns out they really don’t adapt well. Less choice can drive more behavior/purchase/etc.

Hardware guys ship and they’re done – web guys can iterate –

Games guys do this constraint thing well – give rewards, test a huge amount, watch user behavior.

Is Facebook Simple? Yes and no. The applications can be overwhelming, but the social dashboard, keeping track of friends, and photos is easy and well done.
