>>Women like style statements in their web viewing as well as in their wardrobes.<< BK, would sure like to know more about this thought.
>>In the past, compatability page size was always an issue.<< BT, don't understand this factor.
Hard data? Let's face it, what would this crowd believe anyway? By the time data is collected, deciphered and published, the trend would be gone. And there are certainly trends. Is MouseOver one of them? Eventually, I think yes, but for now and the foreseeable (will you be adding spellcheck?) future, I think no.
Without my mouseovers, my visitors are left with slogging through my catalog, page by page, which they won't do. I use the MO to give them an alternative; I've gathered what I imagine they may want into more narrow categories; this is no extraordinary science. Except that when they mouseover, I use that as extra selling space to encourage them to take the chance to click. I use a combo of text with the graphic to advise them of the wonders which lie in wait there for them.
It turns out that we are also part-entertainers. And mouseovers are part of that entertainment. My visitors easily at a 50% rate, choose my mouseovers as their navigational option.
Many mouseovers glow or some such, and I can't speak for them (although I do love them); me, i use the MO for another chance to talk to my visitor with a little pop-up. They definitely bite.
If well done, it's just . . . (thinking) . . . cool.
