if I knew I would be going away on vacation for a couple of weeks and would not be able to have access to post on steemit, I could delegate my steem power to a friend or service and earn some residual STEEM or SBD while I was away.

Great feature here on Steemit.

And it can help smaller guys here, too.

I remember when I just started I had problem with network bandwith because I had so few SP.

And, there was a guy that delegated 100SP to me, so I can post normally without having those problems.
