Hi Guyz,

I can get answer also in google, Bing and from other, but I need you personal opinion on this, what do you guys really feel about this social medias Platforms?

It's similar to different Pizza restaurants: it's all about preference, timing and availability. Meta owns Facebook and Instagram, and both platforms have code that allows them to easily update each other but some ppl just share on one more than another. 

I feel neutral about them all and only care about:

1. How they work
2. How my target audience uses them
3. How I can 'M&M' (market and monetize) from each
