When asked how to describe DSA positively it's a very hard thing to do. This random girl came over to me and asked me about it, no idea who she was or why she asked, but I answered as best I could. It's great if you know everything already and have nothing else you need to learn. It's brilliant if you want 1 or 2 lectures a month where people actually turn up, and it's good in respect that all the lecturers seem to know you by name, even if that's all they do know. That sound about right?!?!?!
