No high hopes, but thought these would be fun and I would pick them on certain chars:

Edges:
World Renowned - Increased chance of your victories being tweeted.
Solid Reputation - Decreased chance of your defeats being tweeted.
OR
Spin Doctor - Does both.

Bonus quote:

Reputation is an idle and most false imposition; oft got without merit, and lost without deserving.
-William Shakespeare

I'd prefer the opposite effect.

I would rather fly under the radar as much as possible to get fights and then not be revenge ganked because people work out from twitter that I got fulled.

I still like the twitter feed. I just don't want to be the food.
