(This question is basic but I couldn't find the answer skimming through meta.)
I read a question, and I want to recommend 2 products that seem to match the requirements: should I leave one or two answers?
In the software recommendation Stack Exchange website, typically 1 answer contains 1 program only, so that users can vote and comment directly on a program (e.g., if the answer contains 1 good program and 1 crapware, casting a vote would be meaningless).
