It's on the wiki, If no land is available when your portal spawns in the nether, you get a small obsidian platform.
you are just unlucky.

After 10:30 PST, my IQ drops to around that of a shovel, please disregard anything I say after aforementioned time, it will likely not make any sense, and is best ignored.
I think that is awesome. Yeah it's more difficult, but it would be easy to see from other portals and one bonus is that the portal is placed in EXACTLY the x,y,z coordinates of your portal in the overworld in relation to the Nether.
Lol, when I first saw that, my first reaction was, holy crap, that looks like my nether realm! I came through my portal, and saw a ton of lava. I started sneaking, and looked down. There were no blocks whatsoever in front of my portal, but, luckily, there was netherrack behind me. My portal had spawned on the edge of a cliff, so I was really glad I decided to be really careful (it was a 100+ block drop, too :SSSS:)
you are just unlucky.

I tried it with terrible results. I gave my wife my glasses for a second, a creeper showed up and now my wife is pregnant.
Stupid 3D..
