> > FB is a ghost town

FB is not a ghost town, you think that it is because no "thought leader" of the stuff you are interested in (tech, finance, business, stock market etc.) has their major presence or main channel of distribution of content on FB as they are mostly on YT and Twitter.

I called it a "ghost town" because none of my friends post on it anymore. There is nothing social about it, it is like a message board at this time.
