As a consumer or a provider? You really need to be a bit more forthcoming with details to what exactly you want to achieve (and maybe what you've tried already).
I haven't tried much because I literally don't know where to start. Everyone just gives documentation on how it works but not exactly what I need to do. I am not up to date on coding anything these days, especially with this kind of stuff.
I run a subscription based forum and just would like it if people quit needing to post the twitter embed code themselves, among other things.
