The Daily Grind: Do you run old raid content?

One of the things that we heard about people doing over the recent holiday weekend was tackling legacy content. Why? Well, what we heard was mostly about how with people traveling, lots of raid schedules were changed. This meant "whoever can show up" groupings seemed to occur, with many of them heading for old raids (like the above Molten Core raid in World of Warcraft) for fun.

Of course, this got us to thinking.... Does anyone just run old content for the fun of it -- at least, beyond the occasional raid-schedule disruption? Are you more focused on progressing in your game of choice? If you do like to check out old-school content, what is it about it that draws you? Did you never do it before? Did you prefer the mechanics? Or maybe you just like the storylines better. Let us know!
