May be, considering the returns, h2o could hire someone to make a modern website
you can't be serious, right? this site looks awesome: don't change a thing.
If modern site = longer page load time, than no thanks, I'm good. Keeping the announcements up to date really shouldn't be that hard, but whatever - it's probably not something that's the biggest issue during 100%/day growth periods. Things will get a lot less interesting pretty soon.
Archiving the thousands of inactive addresses would reduce server load and make things easier on everyone. That should be done real soon.
