This might be the most egregious thread jacking ever....
Franny~ started as StFrancisDkHtr or some other deal, that's where "Franny" came from. He was woodyswat, ilikewoodys and posted something here recently that I think had some woody issue. His MO is generally a troll..... put out some odd question about something, get someone working really hard to solve his problem, the he goes dbag and gets the people taking the internet seriously all riled up.
FF~ Luke L, Nick M, etc. Different dude than Franny, different MO. FF cycles through thoughtful engagement, then goes to aggressive paradigm, then pot stirring, then his characters have historically gone deep end. The new name starts after a cooling off period, and he resets. I think FF has been the longest living moniker and the most focused/productive. While we won't get Old Man and the Slough again, or maybe even a carved pumpkin, FF has been way more engaging than the predecessors.
The primary entertainment value of the two is different.
Franny~ it's in watching the people taking him seriously get suckered in and them losing it
FF~ it's much more in the craft, persona development, etc. When one of the previous characters had Dani (crack addict lesbian wife I believe), that was some serous character development.
