Be wary of chrome extensions Hive account@fknmayhem!! They can read all your website data you visit and in case of Steemit they could very well read your posting keys since you use the website mostly in a logged in state. I wouldn't be surprised if some people start reporting Steem-theft from their wallet at some point.

This would be a better option: http://steemistry.com/steemit-mentions-tool
