Like everything in life, its all enjoyed in moderation and when used as tools, can actually be beneficial. Sadly, some get carried away with this stuff.
For "me" there is some merit in visiting some of these networks rather than painting them all with the same tarnished brush.
Twitter is great mainly for the latest breaking news, oh yeah, and seeing Trumps rants.
Instagram has considerably increased the profile and presence of our business.
YouTube, great for reviews, and How To Vid's.
The rest, FB, Linked In, Snapchat, Tinder et all, are all dead to me.
