Agh, the browser wars are restarting! Let me plump down for Opera, and be a proud member of the 2% (while staunchly standing up with the 99% here in the States, but that's another topic entirely). But I'm happy with Chrome or FF as well, so no badmouthing of anything besides IE from me.
Agreed. I toss 'em into the sites I do, but if I spend more than five minutes on them, that's too long. As Stevie says, descriptions are an entirely different issue. That's what the search engines display in their summaries of your site, so write good ones.
