Well,

That was a colossal waste of time.  Mined for a while and was making some coin.  Then, the dashboard on the pool's site changes.  It no longer shows your shares, your balances, etc.  Instead it shows an estimate of what you will mine in 24h, 7d, 14d.  All of my coins dissipated as well as most of my shares and the site seems to be stuck on block 34804.
