So, I see Dirty F is on the role, so I thought I'd chip in to ask for the worthy 2c of the seo gfy gurus....
css display

dden - a no go for seo or ok?
web2 uses it a shit lot and doesn't seem to get penalised. Quite the opposite, it ranks high. Is the bot js savvy, so that if there is a mouseover to turn that to visible, it isn't penalised, but if it's just there for seo purposes, you get sin binned?
what's the low down, cos I'd like to use it for some "related videos" (6 max) to get maxium keyworditch on a video page....?
--- edit
make that css display:none
pffft - still, the Q is the same
