I think its a good idea to put aside donations for now anyway since the price is what it is, and tbh just having steem laying there isn't better than powering it up, it would probably be better to donate in the future through weekly payments anyway in my opinion. Considering how popular patreon.com is getting where many users and organisations rely on others donating money to them on a monthy basis, weekly will be even better. :)

Hey maybe once Steemit is more known you could even offer them the account to use themselves here? :)
