yeah.
i think the retail stuff is interesting.
look at vix futures, earnings bets, terminal distribution vol trades.
That is basically the stuff I look at now... though not every single opportunity since I have a full-time non-trading job. One other thing I would add to that list is under/over-reactions to news events. Problem is being wrong on delta in these cases makes being right on vol kinda worthless if you aren't hedging.
