Info :
Gavin Andresen has changed the Bitcoin code to block any output with a value of less than 54uBTC:
https://github.com/bitcoin/bitcoin/pull/2577...
This pull defines 'uneconomic dust' as 54.3 uBTC (5430 satoshis, about $0.007 at current prices),
and treats any transaction with outputs less than 5430 satoshis as non-standard (won't be relayed,
won't be mined).
...
I guess the sites that now pay you 1, 5, 10 satoshi per visit will make you wait months if not years before payout
I am prompted to recoin every penny counts as every Satoshi counts !
