A bit off-topic, but I'd like to make a correction: I gave you useful information without an article (the). You could say "the useful article" only if the sentence went on like "which made me understand it fully" or if you were singling out information which was mentioned before: I got a lot of information, but you gave me the useful bits of information.

And the final utterance also should not have a definite article: "Bitpicker, (it's an) interesting article". The part in brackets can be dropped or you can keep the indefinite article, but there is no way you can have a definite article here. You could, in a face to face situation, put a newspaper on the table, point at one of the articles and say "(this is) the interesting article (which we talked about)", but that's all.
