First off, excellent chapter (oh thats new, never wrote that in this fic before .
Okay, reasons this fic is so good/popular (one does not neccesarily equal the other, but in this case it is both.
1 You are informing people when new chapters are up.
2 Word of mouth, one thing about Pokeshippers, is when there is a good AAML/AAMRN around, they tell EVERY Pokeshipper they know about it.
3 You are too darn likable. It is hard not to like an author so kind to her readers.
4 Never have I ever seen responses to reviews in a fic, it was a great idea, and I am sure it helped.
5 You involved us in it by putting all of your reviewers names in a couple chapters.
6 Many side jokes for occasional comic relief, just like Shakespeare used to do.
7 You have the best Luvdisk personallity ever.
8 Uncertainty, it is nice to see a AAML where you don't know exactly what is going to happen all the time.
9 Speaking of which, you had other major elements besides Ash and Misty (this is one of the main reasons I am sure) you had good subplots and such, and a major story which is there for more than "just so there is something else besides romance"
10 You should be writing for TV Tokyo, because this is probably the closest any fic has ever come to the anime.
11 Little things related to previous episodes of the anime.
12 A reason for all this. So many AAML just seem to throw together how every thing started, you did not make that mistake and actually explained it well.
13 Main characters in peril.
14 Dang cliffhangers
15 Everyone is IC most of the time.
16 Not knowing that Ash and Misty will end up together (perhaps the biggest reason of all) I think when I said that they probably will end up together at the end, but that you had done a great job so far so let her be thing, and then you answered it saying yeah, I have done a good job so far, I won't let you down. That (IMO) is when this thing really took off. Before that I think I was the only person who realized that this was not a normal AAML fic, and might not have the normal Happily Ever After ending, but when you said that and other people found out that this was special. That was it.
17 Metal Gardevoir, Gladdecease, me, and a few others who have not let this thing drop past page 3 in over 3 months. If people forget about your fic, that is a problem, I am just stating the truth here that we have kept this thing going really strong.
Whew, I am done. Great fic, keep it up.
