I misread that as in NieA Under 7, and I thought to myself, hey, that's on my watchlist, it's associated with the character designer from Lain.
Honestly, I really just look at lists of anime, in particular the "recommend" section on MAL at the bottom of anime I already like, or the favourites on the user profile of someone who rated an anime I like highly. Sometimes things really stand out to you, and you know you're going to love them just from the name and cover, that's how I felt about Haibane Renmei and Windy Tales. If it looks good it's probably good and if it looks really good it's probably really good. Sometimes things are a bit disappointing, but it's hard to find something you aren't glad you watched.
