Tbh, I don't see how/why Data would be going to put in the massive amounts of time that it takes to
a) make a great scrimming website with all the features that the other 3 (4?) existing options don't have
b) masssively advertise that scrimming website such that (even with tf2stadium around), all the teams will now use it, which never happened with any scrimming website ever in the past (without tf2stadium around)
c) maintain the servers, bugfix the site and interact with the community
all by himself, with evidently limited coding experience, for zero money, all while also getting his Bachelor (could make the site his exam project, but there's still additional work on the way there).
But if he does, nice.
