Can someone point me to a study that answers this question; Does ALL CAPS help or inhibit usability in navigation? I read one article by Jakob Neilson that touches on this saying "Reading speed is reduced by 10% and users are put off by the appearance of shouting." but I could not find the actual study that proved it. Thanks all! Let me know if this question and answers that followed helped you? Much of the research done

In my particular situation, I have a comment form than cannot be used until the user has logged in and joined a specific topic. Then, they can comment on that topic. In your opinion, should I hide the comment form completely, or disable it and prompt the user to complete the necessary requirements. Disabling them saves the user from effortlessly looking for functionality she knew to exist before. So in general, hiding something completely from view just generates frustration. Remember the dynamically populated menus in Office 2000 to 2003? Then you know what I mean (cf. Jensen Harris' blog

Have you noticed that almost every links in facebook have ref query string? I belive that, with that ref , facebook somehow track and study their user behaviour. this could be their secret recipe of making a better usability.

I'm somewhat used to the GUI idiom where when I type something wrong in a text input field a balloon pops up from the field with info about what I got wrong / expected input. It remains visible until I type again. But now I couldn't find any example to point to. Given a JTextfield do you know of any library/code that would display such a balloon when triggered by my keylistener? @see http://www.javapractices.com/topic/TopicAction.do?Id=151 Balloon Tip is a library that does that: balloonTip = new BalloonTip(f, "Tooltip msg"); That was all needed!
