Ah, the MPAA way. It's hard to get the "angry owner" tone out with one swear, one swear says "professional but kind of flustered". I don't like gratuitous swearing either, but I think I got it right with the copy there (at least for my aesthetic).
It's been a while since I read all of it at once, though, I wil re-read and adjust, thanks.
The language is fine. I actually find it much more refreshing than the usual onslaught on buzzword laden services that pop up on HN. You can edit the language as much as you want, the puritans won't be satisfied.
If this is your hobby project, I doubt you are looking for enterprise signups who are pretty anal about such things. This will mostly used by individuals, who mostly wouldn't mind at worst, or be amused by it at best.
Oh I agree with you 100%, it's just that this copy has gone through various iterations, and you need to step back once in a while and read all of it to see if it blends together well, which I haven't done in a while.
I, too, dislike people who try to be funny by cursing, because it feels facile. I just read the copy again now and there were a few cases where the cursing felt gratuitous, rather than for a specific effect, so I have changed those.
This would qualify as PG if it were a movie. I mean, you like what you like, but how much cussing is "just enough" for you?
