I have no idea how many people are making it work at the moment...But I would be willing to wager that in 2 years that number will be muuuuch higher than whatever the number is today. In my opinion it is still somewhat earlier days for Steemit. It's been around for a little over a year.

Buying a little bit of steem regularly could be a good move in the long run if this is something that interests you indefinitely.

Thanks for sharing.

Steem On,
