Our optimization process sucks.
Every now and then someone makes up a thread concerning the optimization of LW, we have a nice discussion, one or the other idea gets a number of upvotes, sometimes quite a lot, but in the end, nothing happens.
What's more, it is predictable that nothing will happen, which kills the motivation to contribute.
- The LW staff (those who hold the authority to implement major changes!) needs to commit a considerable amount of time for the optimization of LW. If necessary, hire someone and make his main job LW optimization.
- The people contributing to optimization threads need to get serious feedback from the staff. It is just frustrating to feel that those who are in charge of implementing changes will not even take the time to think my arguments through.
It is just a tragic waste to put so much time and effort into LW, and about nothing into optimizing it.
As others have said, the only way this will happen is if LW's users make it happen. (Or if MIRI or some other LW-associated entity suddenly gets a big pile of money and can't think of anything more valuable to do with it than paying someone to improve LW.)
To which end, it would be interesting to know: When "unofficial" people have in the past offered to implement LW improvements, what's the response been? Have they done the work? Has it been integrated into the LW site?
It is possible that some potential contributors are put off by the possibility that they'll do a load of work and then find that no one is willing and able and has enough time to look at their changes and put them into action. Does evidence exist that would enable such people to tell how (un)reasonable that concern is?
Only a few recent changes weren't authored by one of the top 4 contributors. That wouldn't discourage me from starting work on a new feature, but I wouldn't spend more than a day or so without testing the waters (e.g. requesting approval for new unit tests).
