I don't spend much time online. But of course I use internet every day. For searching information or for spend my free time. Like my friends I spend about 5 hours online a day. On weekends I spend more, on days when I haven't got much free time I spend less, but most times I spend about 1-1,5 hours at school and 3-4 hours at home.
I usually spend this time online on 2 devices: my mobile phone and my computer.
I don't like using social media with posts. But I use YouTube, that is social media and video platform. Also I use VK and telegram, but more like messengers.
Most time I use WhatsApp messenger. I use it to contact with my friends, teachers and family, but I prefer life meetings more. I think it's more comfortable than WhatsApp.
I don't like posting something online and hardly ever update my profiles, so it's nothing to see on my vk account.
In my opinion social media isimportant for our life. It's a place where people can spend their free time, make money or content. But I prefer online games with friends. It's not worse than social media to spend free time.
