My aesthetic senses have always led me to a preference for button {} over .btn {}, class="foo bar" over class="foo-bar", etc. But I realise I'm in the minority and I need to get pragmatic. The slides have convinced me to check out the video tomorrow, which will be a start.

codeguide.co also looks well worth checking out. At the risk of derailing the conversation further, what's the reason for leaving a trailing slash out of self-closing elements? I recognise it's optional, but including it gives you the option of XML-parsing your HTML; is there a non-aesthetic advantage?
