Usability – happy user peak

Happy user peakEvery experienced web developer will have discovered that too many features leads to confusion for users. This happy user peak chart helps you visualise it.

However, there are ways to squeeze extra features in while maintaining usability and some sites manage to do this well. Flickr and Ebuyer are two examples. Amazon has gone past the peak – I have found myself stuck on amazon.co.uk more than once and then find it impossible to contact them.
