Not everyone joins a pool knowing its advantages and disadvantages. I think most people join initially because of popularity. A pool needs to have an attractive quality to pull people away from a popular pool. A selling point of Slush is that it is the oldest pool and well established. To see quirks like this is disappointing at best and reason to switch pools at worst. Most people who are hashing at lower hash rate pools want to see the network diversified, and I should think others would want to keep people hashing here for the same reason. I recently switched some of my hashing here from HHTT since it closed, so I am new to this pool, and the recent quirks don't speak stability. I'm willing to wait it out, and I'm not "crying" about anything. I would just prefer to not be seeing a consolidation of hash power in just two pools, which is what I think quirks like this will cause.
I'd much rather see BTC Guild on top than Ghash.IO though.
