High volatility inflates the option premium (the higher the percentage of Implied Volatility, the higher the option price), which is usually a good thing for option writers (sellers).
Yes, but as TskTsk noted a few posts above, it's hard to know if the increase in IV is just getting started or if it's topping out. Profits come a lot easier if you've got the edge-skill-mojo to sell volatility at the right time, not just because it's high relative to three months ago or a year ago.
