We are in the process of pushing an updated version of the underlying framework that runs the site today/tomorrow.
There may be some weirdness.
Please let us know in the Tech Outreach thread if you experience any of the aforementioned weirdness (on the site, what you do in your own time is your business) and we shall attempt to solve the problem.
Thanks all!
UPDATE: This is now live, check out that snazzy new loading bar! YouTube eat your heart out!
