Answers in spoiler tags as usual, please.

I found this puzzle while wandering various puzzle pages, but I can no longer remember which web page was the one where I first found it.
ok, i am posting my answer to this before reading any clues or spoiler tags ! i am not sure i'm right but the answer jumped out at me so i'm taking a chance...

Spoiler:

my answer : the next number should be 1113213211
starting from the second line, each line of numbers describes the line of numbers above it, giving the quantity of each digit present, in order, reading from left to right.


now, off to read all the spoiler tags and see if i'm right.
