I want to notarize a SHA256 hash of a document I have. Before ETH I would have used a BTC OP_RETURN transaction service. Since BTC is trying to reduce notary spam, what would be a good ETH notary service that people might recommend that the ETH community doesn't frown upon?

Easiest way I found was to just include the data I want notarized in a $0 transaction to myself in the data field. This is usually used for Contracts, but technically anything can get put in there.

I realize that at some time in the future, the ETH blockchain may choose to prune these bits of data away, but for my immediate need, it will fit the bill...
