Easier for you and other developers to know whats going on, reads better when CSS et al is not available. "Can" work better when using a screen reader so improves your accessiblity. More importantly I think is it gets you in the habit of writing better mark up which is more likely to validate without having to do too many fixes. Simply put its good practise but I would say don't get too hung up on getting 100% right all the time, brain power is better spend on other problems than arguing over weather a dl is better than a ul for a given problem etc.
