Since I am one of those that very rarely speak, let me explain what is happening for me (and I suspect to many others).
I contributed to the community various artifacts: translation of children books, translation of comics, cheat sheets (I'm particurarly proud of the "pro-sumti periodic table") and one of the few (if not the only one) crossword puzzle in Lojban. I did get very little feedback on what I contributed but I did it hoping someone would found them useful at a later time.
Then my interest faded a bit and I devoted my little free time to other things.
Still I see the same thing happening in "waves": a group of people contributes some stuff, then they disappear, someone else picks up those stuff or start something from scratch. And so on ...
I do appreciate what uakci and selpa'i do for the community, and what Robin does! and all the others.
Drastic changes would stop this "waves" as they would make obsolete what has been done already (see the effect of the "great rafsi reallocation") that's why I felt the need of object. Just a little, of course. Since I'm not contributing at the moment, I am not entitled to really complain.
I hope I will have more time (and more interest) to contribute in the future.
