Time for the once a decade Jeremiad?
1. The perfect is the mortal enemy of the good. Are you sure Lojban needs more fixing (or even all it seems to have gotten)? Do you have a clear idea what Lojban is supposed to do and have you really tried to do these things with it? (A large part of what I see every day, aside from new words, are reinventing the wheel without looking at the wheels already turning. I know what lacks I see and know how to fix them fairly
easily -- and backward compatibly -- but the next problem gets in the way).
2. Who has the authority to make a reasonably final decision on what is a real problem and what is a solution? A person? a group? the community (how polled?)? Will everybody (anybody) heed? Most proposed problems gets solved (several times) fairly quickly, then forgotten until (and even after) they come up again. So, where is the record of problems raised and solutions accepted (note: the searchable archives have proven fairly ineffective for this)? And who maintains it, if anyone?
3. [Expanding on 1] While learning the mechanics of Lojban, no real effort has been made to teach Lojbanism, the philosophy (as it were, and in a good sense) behind the language. No one is taken in for long by the older saw about testing the Whorf Hypothesis and the bit about thinking logically doesn't last much longer
(if as long, come to think of it). So people bring all sorts of ideas or ideals to Lojban and, when it does immediately deal with them, either quit in disgust or try to fix it, never noting that what they are out to do is nothing something Lojban was out to do. So many problems are presented and taken seriously that are just beside the point, but are indistinguishable in their fervor from central ones.
4. While anybody may have a good idea and no one should be censored, some people have track records that entitle their views to a more careful consideration that Joe Newby's -- even though Joe may eventually turn out to be right. This is a difficult balancing act but an essential one if progress is not to be constantly diverted by pseudoproblems or wild-eyed (in retrospect) theories.
5. Enough of Lojban is settled syntactically and semantically to do as a functioning language for 99% of the purposes
one might have in mind (much more so than, say, English). More time might be spent on getting some decent teaching aids going at all level (not to disparage what there are, but more and more diverse ones are needed). Prolix Lojban is difficult mainly because of its vocabulary, which has traditionally been ram-fed, rather than in the modern traditional way. But as Pimsleur and the like show, you can get a long way with a hundred words and the basic grammar (both of which are much simpler in Lojban than in French or -- God help us -- English). If you come to a problem, you can look it up or play around a bit -- getting the message across even if the Lojban is a bit iffy. (Toki pona, with 120 words, give or take, and a half-page grammar, has managed to say just about everything anyone has tried to day so far and has managed to be understood at least as well as my French.)
6. Lojban probably isn/t your life, but
work at it proportionally to your sense of commitment.
