Nope. But it begs the question why the miners are mining there. It does no good for their revenue, and it does bitcoin no good to have a few mega pools dominate the scene. The only one benefiting is Tycho.
From reading the forums for a long time, I am convinced it's mostly ignorance. I see a lot of people who think that you earn more Bitcoins in the largest pool. I'm not even talking about variance reduction here, they actually think they straight up earn more.
So, Yeah, Noobs flock to the big pool, No doubt, Can you change that? Prolly not, Why? Noobs are noobs. They just have to Learn to Switch.
On the topic of Variance, People fear smaller pools due to the possibilities of one day they earn .5, The next day they earn, 1, The next day .2, So they get spooked and goto the Lowest Variance pool, Wich is deepbit, (correct me if im wrong) Majority of people need to SEE stable income to feel safe when leaving some "valubles" at ANON's (tycho/slush/pedo) "House", when they see an unsteady flow of funds, They think somethings wrong, Or that they could do something to Steady it, Wich makes them feel 'Insecure'.
I sure as fuck didnt want to point my hashing power aaaaaaaaaanywhere when i first started, I thought bitcoins were some Police related "IMA CRACK YOUAR HDDS WITH YOUR OWN COMPUTING POWER" type of dealio.
So i ran solo for Daaaaaaaays with NoShow, swaped to Slush, Didnt want to wait 120blocks just to touch my funds (and when i saw an INVALID i panicked and ran thinking slush had stolen a full block, Again this is NOOB behavour) So i went to deepbit. Loved it, So i went looking for something better, Found BTCguild, thought the idea of multiple servers was Swag... Untill the DDoSing started (pretend your a noob, You dont know wtf a DDoS is and you dont know WHY your hashing power is all failing when aimed at a Specific spot) So, Scared again, I ran back to tycho's pool, Wich had active chatter in the thread about the pool being down and that the admin was "fixing it". And he did.. So since then, I have had Little reason to leave.
Noob=Run to deepbit
Learner=Experiment with pools, Will prolly choose a 0% one like BTCguild or Eligius
Experianced dude= Might chose Bitclockers (1%,prizes,livesupport) or perhaps something todo with Merged Mining
Guys who know what they're doing=P2Pool,Solo,Poolhopp
People who dont like variance=Deepbit/Slush/BTCguild
EDIT: So i just went around testing pools. And deepbit has the best latency for me, That alone is reason enough for me to stay.
