All work and no play is not really a good two way communications to live life. You might be a workaholic and love to work all the time, but once in a while it is good to give yourself a break. And that little break can rejuvenate you and make you a better worker.
Surveys are by nature interactive. In a way they are a identify features of two way communication. You ask your readers some questions and they answer you. My favorite way to use a survey in email is to ask them a few questions about a certain topic to see if they are interested in learning more about it. I like to keep some of the questions open ended to get my readers to tell me exactly what it is they are interested in. For example, I recently surveyed one of my niches about healthy eating and asked them what their biggest challenge was when it came to healthy eating. My readers loved filling out the survey and knowing that I would read each entry.
The first thing I need to get is a monitor for baby (like a 2 way communication alarm). I want to know that baby is asleep and still breathing (when things at last go quiet), be warned when they stir and need care. That's when Dad can go and see if it's suckling time or nappy changing time. We talked about splitting the duties and Dad has the nappy changing and I have baby brought to me when they need suckling. So I do the bit that he can't and he helps with the bit that he can do. Sounds like a good deal to me!
Instantly I noticed there was now a most uncharacteristic whining quality to my voice and resolved to shut down communications for the day. I drove over to the drug store and naturally waited on line behind someone having about 10 minutes of cash register/checking/credit card/fumbling candy bars/dropping small change problems, which another day would have found me much more sympathetic. While in line, the cell phone rang about the Olds.
With regards to techniques of communication preferences, iMessage gives users a lot more selections than just being to call or text around the Apple iPhone 5. This is a thing to watch for on the highly anticipated smartphone.
