I envision a group of conversations that wander cheerfully all over and do not have to stay "on topic" because the topic changes, too. I think of it as being just like conversations one has when sitting down to chat with friends. You start with one thing and wander to another as the thoughts come to you. So, as in discussing recipes, you start out talking about Chicken Marsala and move on to sharing recipes for White Chocolate Raspberry Cheesecake and Jade Martinis and end up talking about the Pompeii exhibit at the museum. Or, you start out talking about new cars and end up wondering if wind turbines and solar panels are practical for your homes. Whatever. That's how conversations go. But, sticking to the topic that started the posts is not a big deal. Wander. Talk about what comes to mind after reading one of the posts. Reply with those thoughts. Let the conversation be the way we sit and talk with our friends at the dinner table when the dishes have been cleared off. Rules: Don't get political. Don't flame. Don't be crude. Don't insult anyone because of race, creed, color, religion, or political leanings. No politics. (Did I say that already?) Be kind. Be compassionate. Be friendly. Chat with each other. Trade stories about your families, your friends, your job, your life. Have a good time and enjoy the company.
