Hey TMIT, I dont have a youtube account and I dont want one, so I comment on your SC2 videos here. I am not a player my self but I watched the pro games for about 3 or 4 month now on sc2casts.com and i might have some hints for you even though, I dont know if they play out.
In your first diamond video, you asked for help how to save your second hatchery. Well, I guess build a second queen as soon as you build the hatchery and let it place a creep tumor on its way to the hatchery. Queens are maybe not super effective against reapers, but with some micromanagement you would have kept both alive and connected your two bases without loosing larva. And than build a spine crawler down there as fast as possible.
