It seems to be common on the web to provide users with some visual element on the page to either print or bookmark a page. This is all well and good (and probably doesn't hurt for the most part), but I question its effectiveness at causing the intended behavior.
Is there any evidence to suggest that this causes an increase in bookmarking/printing behavior? Similarly, is there any evidence that users will use this method rather than the browser's default interface for the functions?
I am really looking for user research with actual results, rather than anecdotes to answer this question.
Thanks, Joseph Mastey
