On the bitcoin subreddit, I have noticed lots of advertising at the top from bitcoin suppliers - I wonder if we can interest them in purchasing steempower and then using a bot to upvote any post that has their keyword in it?

After all mainstream advertising works on keywords, so steem up-voting could work the same way. For example say shapeshift bought steempower and then upvoted any post that had "shapeshift" in the text. I think that could create a certain buzz in the cryptocoin community.
