Detailed post I must say. You started being a social medialist so to speak at an early early. I can relate. The spirit that came with chatting especially while using a button phone was high.
Just as you've said;

Initially, when I start chatting on 2GO, I don't mind chatting on High Way due to the type of friends I am chatting with then.

To be frank, I do this occasionally so as not to miss any gist most especially during the day. From your post, you've share how impactful social media has been to you in the communication sector as you'll not have to burn your airtime in saying a greeting or two. Social media has undoubtedly added significant value to our lives and has made communication more accessible and convenient. Thanks for sharing this post with us. Wishing you best of luck in this contest. I also participated in this engagement challenge.
