There was a sudden exodus of talent, which reduced posting frequency, and took the wind out of the sails.
I’d be wary of post hoc ergo propter hoc in this context. You might also have expected that by leaving for other projects these posters would create a vacuum for others to fill. It could be worth looking at why that didn’t happen.
One interesting thing is that at one point post-Eliezer, there were two “rising stars” on LW who were regularly producing lots of fascinating content: lukeprog and So8res. Both stopped regularly posting here some time after they were recruited by MIRI and their priorities shifted.
