Indeed. Though I would expect memories that connect to things the recipient already has experience with to be more readily accessible than memories that don't... though that still implies herring in ton lots. (Ew.)
Also, being introduced to a technique does not entail using it, especially when one's social/emotional habits suggest otherwise. (More's the pity, perhaps.) Most, quite possibly all, of the recipients will treat it as a potentially useful technique for evaluating their own biases, should they ever actually decide to do the hard and uncomfortable work of doing that, which they likely won't.
Which means it's entirely plausible that when the dust settles, everyone's allegiances will be precisely what they were before (though the fact that Aro didn't want the information disseminated suggests that this isn't guaranteed).
Still and all, though, the period while the dust remains suspended, when loyalties are suddenly unreliable, should be... interesting. Though we may not get to actually read about it, as our viewpoint characters are now elsewhere.
I'm not sure if you've read Twilight Canon TheOtherDave, but Aro did kill his sister and Marcus' mate Didyme to prevent Marcus from leaving the coven, which was what Didyme had been wanting to do. I seem to remember this being said in Luminosity or Radiance, too, but maybe my memory errs.
In any case, Marcus is certain to go apeshit if he learns that particular piece of information. I doubt many are loyal to the catatonic man though, especially if Chelsea has been preventively cutting all his relationships - with the exception Aro's, Caius' and hers -, in c...
This is Part 2 of the discussion of Alicorn's Twilight fanfic Luminosity.
LATE BREAKING EDIT: Part 3 exists now, so new comment threads should be started there rather than here.
In the vein of the Harry Potter and the Methods of Rationality discussion threads this is the place to discuss anything relating to Alicorn's Twilight fanfic Luminosity. The fanfic is also archived on Alicorn's own website.
Here is Part 1 of the discussion. Previous discussion is hidden so deeply within the first Methods of Rationality thread that it's difficult to find even if you already know it exists.
Similar to how Eliezer's fanfic popularizes material from his sequences Alicorn is using the insights from her Luminosity sequence.
The fic is really really good but there is a twist part way through that makes the fic even more worth reading than it already was, but that makes it hard to talk about because to even ask if someone is twist-aware with any specific hints is difficult. The twist is in the latter half of the story. If you are certainly not post-twist and want to save the surprise, then you should stop reading here and fall back to Part 1 discussion or to the fic itself.
If you think you're pretty sure you are post-twist and are safe to read the rest of this, try reading this rot13'ed hint and see if what you've read matches this high level description of the twist...

If the answer to the hint is obvious, then just to be sure that there is not a double illusion of transparency at work, here is the cutoff point spelled out explicitly:
