digeros, what block is your client on?
We are currently at 8415:
{
"blocks" : 8415,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"difficulty" : 0.75582133,
"errors" : "",
"generate" : false,
"genproclimit" : -1,
"hashespersec" : 0,
"networkhashps" : 26487206,
"pooledtx" : 0,
"testnet" : false
}
Yes use a lot of nodes once you are synced, but too many bad nodes can make you download the wrong chain or unable to sync.
Edit: Digeros, you must be on the same chain as us since your nodes are the same as mine. (Again, I think this is the correct/official chain)
update:

{
"blocks" : 8544,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"difficulty" : 0.47088875,
"errors" : "",
"generate" : false,
"genproclimit" : -1,
"hashespersec" : 0,
"networkhashps" : 15196882,
"pooledtx" : 0,
"testnet" : false
}
so I am only supplying 1/15th of the mining hash rate so I could not have created a fork.
