I want to use comments on the internet to gather user requirements.
I plan to collect these comments, read them and decide what the person wants based on what they've written. These list of "wants" will form the user requirements.
For example:
John: I hate the way the program keeps asking me if I'm sure I want to exit.
Could form the requirement:
An option to disable exit confirmation prompts.
What's a suitable methodology for this? I need a process to follow or guidelines to do it correctly. Is it classed as qualitative research?
