Yeah, I've done a few tag duels with UE and some other friends on YGOPro. Doing our duels on that, while quicker and easier, won't really leave much room for creativity in our posts. That or we'll have like, four different people saying different things about something. Not to mention that if you wanted to write the post you'd probably have to keep replaying the replay over and over again to catch key moments...

I could be wrong of course, but that's the way I picture it as of now.
