The whole "LFS is dead"-thing is plain silly since it's just in your head. If you think so, you are dead, as a racer. LFS is still alive and kickin as it has always been. Goes over my head how to blame your own lack of engagement on a product that is still the same fantastic piece of software that it's always been.
It's alright to loose interest, people do that. Whether you ski alot, surf alot, baking cookies or making babies alot, you may loose interest and move to another ego-expansion hobby. It does not mean skiing is dead, or baking cookies or making babies is dead, does it?
No offence, but some peoples way of thinking is beyond me...
