I am designing a web app in which people can come in and rate "objects" and comment on them. I know that the easier it is for the user to perform the main activities the better, but I was wondering if there's any documentation or resource to which I can refer in regards of how many clicks are recommended.
Perhaps too few ain't the best, perhaps a fixed number has been set (e.g. no more than 4 clicks, 2-3 recommended).
What should I be looking for in this subject?
Answer
See Neilsen's take here: http://www.useit.com/alertbox/interaction-elasticity.html
Note he warns against focusing on the number of clicks - he takes the approach (as Peter of the Corn noted in his post) that it's the ease of clicks that really matters. He also adds that context plays a role in what is acceptable, and that you need a good understanding of why a user must click and what happens when they click to know what is acceptable.
Scott Hamill at UXBooth posted this view: http://www.uxbooth.com/blog/stop-counting-clicks/
Given the name of the article I'm not sure there's much more to say, except he quotes research that shows how essential it is that the user feels a click was worth it - if each click provides some measure of success in a task, you don't need to bother counting.
