I nominate a query about mining a small amount on p2pool in order to keep it finding at least a block a day. In fact, with p2pool, if they are able to mine more efficiently than the average, they can potentially earn more than solo mining.
P2pool currently has a 30.2 hour average block time. Helping keep p2pool alive is beneficial to the community and if the operators can achieve lower latency than the average the payout should beat solo mining[1].
