Wetfish might not exist, and even if it did, it would be very different.
Without 4chan I would have never met castalia, haitani, justin, treefire, or gris.
Without justin there'd be no wetfish forums.
Without castalia there'd be no !slapanus and no svchost and no Mozai.
Without treefire there'd be no Soupwhale, and therefore there'd be no yam, libfud, Rothen, Frob, KittyKatt, or Weazzy -- all users who came from Soupwhale. By the way, Soupwhale got 90% of its members by offering free SSH accounts to /g/ users on 4chan...
Kate, emcy, wiiam, and oranges all came from Tox, the open source chat project, that was started on 4chan's /g/ board.
Without 4chan there'd be no 420chan, which means pibdgaf would have never existed either.
That means no kakama, heath, mj, loaf, solo, spidey, olmec, shelby, svaj, or sonatia.
If I never met spidey, I might have never heard of Teeworlds.
Heath and MJ are the reason I met my husband, so I might not even be married if it wasn't for 4chan.
So yeah, I am very thankful for 4chan. It's changed all of our lives.
