Snappa is a great program for the fastest, easiest ways to make social media and online graphics! I've used it for some time (in fact, all the graphics you see in the sidebars of this website were created with it), but I like to use something for a while before I recommend it because I'm sure that many of you have had the same frustration I have where someone does this raving recommendation of a program and with great excitement you go to it and after paying for it realize it is a piece of junk and not only that you signed up for something that keeps wanting you to upgrade or buy more junk from them. That won't happen here as we don't take any advertising or affiliate payments (often the motivation for rave reviews).
Below is my little overview of it.
Here are some additional videos done about Snappa, just click the link below them to go to them.
