well, I am going to reply to easy things first, so let´s go with it:

> Fics that dealt with that should be pretty common 
they are and I say this with the confirmation from one of the staff members. I have written down some notes and got informed of what trends used to happen around the early years. So yeah, you are absolutely right with that statement.

> It still sounds interesting tbh honest. A thematic crossover could be kind of fun, especially if it's lightly obscure. Sounds like something up my ally even if it's not my normal taste. Which I have no idea if it is or not.
you´ll see but I simply hope that it becomes an enjoyable experience throughout the whole story. I am aware of its length so I´ll have to make it appealing for rewarding that effort of being interested in reading it.

 
> In a single day?
yeah, from 3 PM until 00:30 AM. I have been taking breaks of course and I went outdoors for an hour or two but it was clear that...as soon as I noticed that I could reach the end by writing a little bit more, I stayed awake until I finished it. I didn´t feel like replying to anything except informing about the situation.

> That probably beats even my early proto fic for amount of words written in a single day which was done off and on over the course of 3 (?) years.
well, I cherish that appreciation of beating your record of words for a fic written during a  much longer period. How much length does your proto fic have by the way?

> and so am I today (fortunately it is just outdoor this time.)
I did that today as well. I have been completely out there with my friends in a fair actually. I had tons of fun and despite your worries about me for what has happened, I eventually forgot about those unintended events until I arrived back home at 8:30 PM or so. 

> I'd say it depends on what drives you to go further. How much is internal and how much is external.
internal...well, considering that /endpone/ consists in two or three users, this stuff matters because something has to be posted.  About the external influence, I caught the staff of Fimfiction by surprise. I suppose that this event counts and that lucky GET that is mostly an anecdote in order to feel achieved. 

I am not aware of the external influence nor I control it. In fact, with very few people, it can get too much out of hand easily if things are done incorrectly.

> Funny thing on this whole fic. I found some notes today on me considering making a fic based around obscure fairy tale stories. Very different than this but a sort of similar idea.
that´s quite cool. In fact, MLP is quite useful at attempting any random ideas that you have left out and in some way, they are restored in a ponified version. That´s what one calls inspiration even though it reaffirms the phrase of: nothing under the sun.
