I think that time spent towards improving your financial standing is a reasonable use of social media, as long as it's not getting in the way of other aspects of your life. The great thing about social media is that you can choose when you want to use it (24 hours in a day, 168 hours in a week!), so when effectively used, you can time your usage to what's truly best for you.

Easier said than done. I have a lot of work to do in this department. In fact, I should not even be here right now lol!
