I'm looking for any resources or tips on selecting good icons for functions unique to a certain web application. I personally don't design icons myself, and think I could be successful using those already out there for purchase.
If anyone could give insight on a couple of things, that'd be great, too:
1) Should icons on a toolbar always be labeled, or will a user be able to learn them after using the application regularly?
The topic of soliciting mass user feedback regarding the usability of web sites and applications continues to pop up for me. Primary stakeholders ask the question, "Why don't we just send a link to a survey in our newsletter to all our registered users?" or, "Let's add a feedback link or a thumbs up/down clicker to our new beta releases."
