This plug-in is advertised as being easy to set-up, but there are no instructions for how to get the Facebook app you are apparently supposed to get. I tried to do what I had to, which apparently includes registering as a Facebook developer, but in order to do that, you apparently have to have a cell phone texting plan. Nowhere in the set-up instructions or FAQs is this mentioned. There is no discussion of what the work-around is if you don't have a cell phone texting plan (I don't have one).
I was shocked to see that this is the official Facebook plug-in for WordPress. Is this seriously that the best that Facebook can do for the most popular website platform out there?!?!?!?
