Currently there's about 13 thousand Ravenclaw Eagles, 10 thousand Hufflepuff Badgers, 10 thousand Slytherin Snakes and 10 thousand Gryffindor Lions.
For some reason there's always more Ravenclaw than the others. Don't know why. Hufflepuff has the second most players and Slytherin and Gryffindor are always about the same.
Right now, there's A LOT of complaining. "Pottermore is disappointing." "I wish I was in __ house." "There's nothing to do." "This is glitching." etc. ._. Gotta be patient.
A lot of friendly rivalry between Gryffindor and Slytherin. A lot of AVPM quotes. XD And a lot of Hufflepuff love. Especially from Slytherin.
For me, honestly, it was more like, Slytherin first then Ravenclaw followed by Hufflepuff and then Gryffindor. P:
House points wise... well, Slytherin is in first, then Gryffindor, then Ravenclaw and then Hufflepuff. Slytherin and Gryffindor bounce back and forth a lot. Not once has Ravenclaw or Hufflepuff moved from their spots.
By the way, if you guys have an issue with my spouting so much I can always edit and take out some stuff that may seem like spoilers. xD I don't want to ruin it for anyone! D:
