This character launched off of a public thread.
Seriously, everything this character came to be was because of one
singularly awesome public thread. It was a springboard I've never experienced before. What was most satisfying however is that it had an actual conclusion, where all loose ends were closed up and packed away for next time. Then that thread, lead into a couple of private threads, an invasion thread, viola: psychopathic warlord of the west.
That however, is an extreme rarity.
I've been itching for another public thread for a long time to increase my pool of writers I know... unfortunately there is a scarcity of public threads these days, and I can't find one to join. Maybe it's because often times my characters are too well connected to politics, too well known for brutality, or have some pre-determined reason for absolutely not fitting in with the given situation.
I feel like public threads, are best when used with absolutely fresh characters and there is a definite directive of what sort of things to expect, rather than leaving open ended.
