@Gour- The whole point of SO is you can usually find what you're looking for, and if not- your question will be quickly answered and easily found by the next person. That, and the ability to close redundant questions means you build a quality knowledgebase- something that doesn't happen with irc/twitter/google groups.
Other benefits of SO: - Ability to distinguish between questions, answers, and comments - Ability to *edit* questions and answers - Ability to SORT BY VOTES - Ability to save and reference favorites - Ability to search for your issue without wanting to dropkick the screen Google groups is missing the big things and fails on the little things that make SO so effective.
