I think the comm code is the same as the user one.

A br is a break, it's just plain ass old code like hitting enter. A div is a divider, you use it when you're coding CSS more, it's more like making a box around something. Like it defines a section. They're like totally different. So yeah. Don't use divs. You aren't coding any complex ass stuff, I didn't need to use 'em once until I got my new gig doing CSS.

Actually the real difference (at least for me as a web writer) between b and strong is that using strong is an accessibility issue.
