I think you're going a bit far with this. Not everyone who works on fan translations gets exhausted from TLing/editing/hacking. A lot of people in this community genuinely enjoy what they do. I personally am in the military working normally 45 hour work weeks, sometimes extending into 84 hour work weeks. When I come home, I play some DotA 2 with my friends, but there's a lot of downtime when it comes to playing with friends, so you know what I do to entertain myself during that time? I start working on the editing project, and it's quite frankly, relaxing. I get an hour or two of work done per day, which in comparison to many people out there, is quite a bit (though nowhere near what some people in my group do).
It's different for everyone. For you to insinuate that certain people can't handle certain tasks is a bit presumptuous. I've seen leaders of successful projects of all types. Some are exactly how you think a leader should be, such as being dedicated, fair, and all that. Some leaders are lazy cunts who show up once in a blue moon because they have managed to land the jackpot when recruiting members. I've never seen the role of the leader in the project as ever being a problem. Who cares if you're a hacker/editor/TL? If you are a leader that takes the time to make sure the project is a success, nothing else should matter. Hell, you don't even need to be passionate about the project. You just have to... well... DO it, and do it RIGHT. In my mind, that's the only requirement of a leader.
And this is all assuming that I think that assigning a leader is important. Which I don't. Rather than assigning one, I think having a leader naturally reveal himself as you work on a project is much more beneficial. I realize there might be internal strife if you don't assign a leader, but if there's that much conflict in the first place, you have bigger problems than not assigning a leader. We're all grown adults (hopefully). We don't need someone at the top demanding things from us when we're working for free. I want to be part of a team, not a hierarchy. Anyone can organize things. Anyone can recruit people. Anyone can receive people in IRC and see if they fit the bill. Over time, the people that can perform this task will reveal itself, and you can let them be the sole recruiters. You don't need to smack the label of leader on them.
Anyways, I said what I wanted to say. Please don't take any of this personally. I just think you're sending the wrong message to the community.
