Like most people I spend a lot of time online talking to people. Some strangers and some friends.. This is our reality nowadays.. We work, take care of our families, social network and maybe go out on occasion for some fun in order to relieve ourselves of our mundane lives.
As adults we need some time to socialize and like many people who have children know it isn't always easy to breakaway whenever you want so you make the most of it by socializing with other adults online. I think this is okay to do as long as you don't forget to take time to communicate with your loved ones that are in your house and spend time with them as well. I think sometimes spending too much time online can lead to people around you feeling as if they aren't important to you because you are constantly online. I have seen a lot of families break down due to this. So I try to keep focus on people around me also..
Luckily, my husband and I are both on Google+ and share things with each other that we find interesting on here... Feel free to say hi..
