Why do you think this should be prevented?
It's a waste of resources.
For example, if the LessWrong website becomes boring and people move somewhere else, they will again have to design the web page, implement technical features, etc. Even more resources lost if the same thing would happen with MIRI or CFAR. Not only the money and work would be lost, but also prestige and contacts; some useful people would probably be left behind...
There are more options than just "go away a start again" or "grumble". But these two are the easiest options, which is why people have to choose between them if they are not strategic.
It's a waste of resources.
Only from the central-planning point of view.
In a fluid and dynamic system the fact that something was useful a couple of years ago does not mean that it's still useful now. Your "waste of resources" is re-confirmation that X is still useful and can draw people, otherwise it's deadwood and should be discarded to die in a fire.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
