Throwing links as an answer (instead of using them as an addendum or because it's a valid source) is considered bad practice in discussion since usually they're not a direct rebuttal to specific points made.

If you were making a detailed argument about the issues with unregulated capitalism, and I would just respond with "Go read some Mises", it's just a lazy cop-out that doesn't address the problems you're presenting and lowers whatever value the comments may have to a reader, even if I had a point or not.
