My Yahoo Pipes results always disappear next day after the creation;
It has happened now and I remember the same was with my previous website:(
Read the sticky.
sticky doesn't matter, I can create some number of disappearing feeds or may be they are delaying...
I am looking why they ALWAYS disappear, as a low of Murphy!
I cannot help you then.
What is the yahoo username you used to create those Pipes?
He/she won't fall for that old trick.
