I'd would be very handy for sure, I use an e-coin linked to PayPal for small online purchases (e-coin is another Bitcoin debit card) but only when I need to. A few dollars a week from steem isn't really useful for day to day spending IMO.

What I do though, is transfer steem to Bitcoin via bittrex, deposit Bitcoin into a USD hedge account with a forex trader, and then trade currencies to generate a bigger return. Turning $20 into $100 over a month is better than spending $20! :)
